| In the Linux kernel, the following vulnerability has been resolved:
pmdomain: imx93-blk-ctrl: Extract PHY as shared domain for DSI/CSI
The MIPI DSI and CSI domains share control bits for clock and reset, which
can lead to incorrect behavior if one domain disables the shared resource
while the other is still active.
To fix the issue, introduce a shared MIPI PHY power domain to own the
common resources and make DSI and CSI its subdomains. This ensures the
shared bits are properly managed and not disabled while still in use. |
| In the Linux kernel, the following vulnerability has been resolved:
pmdomain: mediatek: Fix possible nullptr KP in HWV cleanup/on-check
Should probe fail for HW_VOTER type power domains, this driver was
unconditionally trying to perform cleanup for DIRECT_CTL domains,
but only after checking if the target domain is powered on... with
the DIRECT_CTL scpsys_domain_is_on() code again.
And there's more: the scpsys_domain_is_on() function is also being
unconditionally used in the probe path, for any power domain that
has flag MTK_SCPD_KEEP_DEFAULT_OFF!
This bug was never experienced by anyone because the HWV domains
never failed probe, and because none of those is declared with the
aforementioned flag - but it's still something critical.
In order to fix this, add a check for MTCMOS Type and, based on
that, call the correct functions for an "is on" check, and also
do the same for the cleanup path, calling the correct functions
for the "power off" action.
For the latter, since there's a call to pm_genpd_remove() right
before calling power_off, be cautious and add a variation of the
power off functions (with a _internal suffix) for those to get a
pointer to scpsys_domain instead of one to generic_pm_domain as,
even if that's still working, this is way too much fragile and
would break at some point. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: free mlx5_st_idx_data on final dealloc
Workloads that repeatedly allocate and release mkeys carrying TPH
steering-tag hints (e.g. churning RDMA MRs) leak one
struct mlx5_st_idx_data per cycle; kmemleak flags it as unreferenced
and the kmalloc slab grows over time.
When the last reference to an ST table entry is dropped,
mlx5_st_dealloc_index() removed the entry from idx_xa but the backing
mlx5_st_idx_data allocation was never freed.
Free idx_data after the xa_erase() so the lifetime of the bookkeeping
struct matches the lifetime of the ST entry it tracks. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btrtl: validate firmware patch bounds
rtlbt_parse_firmware() copies patch_length - 4 bytes before appending the
firmware version. A malformed firmware patch shorter than the version field
can make this subtraction underflow and turn the copy into an oversized
read and write during Bluetooth setup.
The existing patch_offset + patch_length check can also wrap on 32-bit
architectures. Validate the patch length and range without arithmetic
overflow before allocating or copying the patch. |
| In the Linux kernel, the following vulnerability has been resolved:
memstick: ms_block: reject a card that reports too many blocks
msb_ftl_initialize() computes the zone count from the card block count
with no bound:
msb->zone_count = msb->block_count / MS_BLOCKS_IN_ZONE;
...
for (i = 0; i < msb->zone_count; i++)
msb->free_block_count[i] = MS_BLOCKS_IN_ZONE;
msb->block_count is a card value. msb_read_boot_blocks() reads
number_of_blocks from the card boot page and byte swaps it.
free_block_count is a fixed int[MS_MAX_ZONES]. MS_MAX_ZONES is 16, so the
valid indices are 0 to 15. The init loop above indexes it by zone_count.
msb_mark_block_used() and msb_mark_block_unused() index it by
pba / MS_BLOCKS_IN_ZONE, for pba up to block_count - 1. A card may report
up to 65535 blocks. A block_count above 8192 (MS_MAX_ZONES *
MS_BLOCKS_IN_ZONE) lets the pba index reach 16. That writes past
free_block_count[] and corrupts struct msb_data. A larger count runs the
init loop past the end too.
A real Memory Stick has at most 16 zones. So it has at most 8192 blocks.
msb_ftl_initialize() now rejects a card that reports more than
MS_MAX_ZONES * MS_BLOCKS_IN_ZONE blocks. |
| In the Linux kernel, the following vulnerability has been resolved:
ipvs: reload ip header after head reallocation
__ip_vs_get_out_rt() calls skb_ensure_writable() which may
reallocate skb->head. |
| In the Linux kernel, the following vulnerability has been resolved:
reset: sunxi: fix memory region leak on ioremap failure
In sunxi_reset_init(), when ioremap() fails, the memory region obtained
via request_mem_region() is not released, leading to a resource leak.
Add an err_mem_region label to properly release the memory region before
freeing the data structure. |
| In the Linux kernel, the following vulnerability has been resolved:
powerpc/uaccess: correct check for CONFIG_PPC_E500 in mask_user_address()
mask_user_address() incorrectly checks for CONFIG_E500 instead of
CONFIG_PPC_E500, causing mask_user_address_isel() to not be used on
E500 hardware. Fix the check to use the correct name. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: validate EHT MLE before MLD ID read
cfg80211_gen_new_ie() copies ML probe response elements from
the parent frame when the parent EHT multi-link element has an
MLD ID matching the nontransmitted BSSID index.
The code only checked that the extension element had more than
one byte before calling ieee80211_mle_get_mld_id(). That helper
assumes a BASIC MLE with enough common info and documents that
callers must first use ieee80211_mle_type_ok().
Attack chain:
malicious AP sends a short EHT MLE in an MBSSID beacon.
cfg80211_inform_bss_frame_data() stores the copied IE buffer.
cfg80211_parse_mbssid_data() builds the nontransmitted BSS IE.
cfg80211_gen_new_ie() sees the EHT MLE in the parent frame.
ieee80211_mle_get_mld_id() then reads past the IE boundary.
Validate the MLE type and size before reading the MLD ID. This
matches the contract required by the MLE helper and rejects the
short element before any internal MLE fields are accessed. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ieee80211: validate MLE common info length
ieee80211_mle_common_size() uses the first common-info octet as the
common information length for all known MLE types. However,
ieee80211_mle_size_ok() only validates that octet for Basic, Probe
Request, and TDLS MLEs.
Reconfiguration MLEs also skipped the length octet when calculating the
minimum common size, and Priority Access MLEs skipped validation of the
advertised common information length.
Account for the Reconfiguration common-info length octet and validate
the advertised common information length for all known MLE types. Keep
unknown-type handling unchanged.

| In the Linux kernel, the following vulnerability has been resolved:
wifi: mwifiex: fix permanently busy scans after multiple roam iterations
In order for the firmware to sleep, the driver has to confirm a
previously received sleep request. The normal sequence of evets goes
like this:
EVENT_SLEEP -> adapter->ps_state = PS_STATE_PRE_SLEEP -> sleep-confirm
-> SLEEP -> EVENT_AWAKE -> AWAKE.
Before sending the sleep-confirm command, the driver must make sure
there are no commands either running or waiting to be completed.
mwifiex_ret_802_11_associate() unconditionally sets
ps_state = PS_STATE_AWAKE when it processes the association command
response, outside of the normal powersave management flow. If
EVENT_SLEEP arrives while the association command is in flight,
ps_state is PRE_SLEEP when the association command response is parsed,
and the forced AWAKE overwrites it. The deferred sleep-confirm is
never sent.
A subsequent scan_start command is correctly acknowledged, but the
firmware doesn't generate scan_result events. The scan request never
finishes, and additional requests from userspace fail with -EBUSY.
After testing on both IW412 and W8997, I could only trigger the bug on
the IW412 and observed the firmwares behave differently. On the IW412
the firmware still sends EVENT_SLEEP while the authentication /
association process is ongoing. A W8997 under the same
conditions seems to suppress power-save for the duration of the
association, so PRE_SLEEP never coincided with the association response
even after extended periods of testing using the loops
described below (>12hours).
On the IW412, the delay between commands that triggers an EVENT_SLEEP
was empirically determined to be ~20ms. This delay can naturally occur
when the driver is outputting debugging information
(debug_mask = 0x00000037), in which situation the busy scans issue is
repeatable while running "test 1)" as described below. If the delay
between commands is less than ~20ms, the firmware stays awake and
the issue was not reproducible running the same test.
The host_mlme=false path also behaves differently. In this case, the
entire authentication / association transaction is executed by one
command (HostCmd_CMD_802_11_ASSOCIATE), and the firmware doesn't emit
EVENT_SLEEP while the command is running.
Remove the assignment so the ps_state is only manipulated in the paths
that are related to powersave event handling and on the main workqueue
for correct sleep confirmation.
The following loop tests were performed (with debugging output enabled):
1) force roaming between two AP's, one 5GHz and one 2.4GHz, same
SSID. Use wpa_cli to trigger the roaming behavior, sleep 2s
between iterations.
2) force a disconnection to AP 1 and a connection to AP 2, test
scan. Use wpa_cli to trigger the connection changes, sleep 2s
between iterations.
Each test ran in each device for at least 3 hours. |
| In the Linux kernel, the following vulnerability has been resolved:
mtd: virt-concat: free duplicate generated name
Every MTD registration runs mtd_virt_concat_create_join(). Once a
virtual concat has already been registered, the function builds the same
name again and takes the equal-name branch. That branch skips to the
next item without freeing the newly allocated string.
Free the temporary name before continuing. |
| In the Linux kernel, the following vulnerability has been resolved:
mtd: mchp23k256: use SPI match data for chip caps
The driver stores chip capacity information in both the OF match table
and the SPI id table. Probe currently uses of_device_get_match_data(),
so a non-OF SPI modalias match falls back to mchp23k256_caps even when
the SPI id table selected a different part.
Use spi_get_device_match_data() so SPI id-table driver_data is consumed
when OF match data is absent. This keeps the existing default fallback
while avoiding the wrong MTD geometry for id-table-only matches. |
| In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: lpc32xx_slc: fail DMA transfer on completion timeout
lpc32xx_xmit_dma() waits for the DMA completion callback but ignores
wait_for_completion_timeout(). A timed out DMA transfer is therefore
unmapped and reported as successful to the NAND read/write path.
Return -ETIMEDOUT when the completion wait expires. Terminate the DMA
channel before unmapping the scatterlist so the timed out transfer cannot
continue to access the buffer after the error is returned. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-esdhc-imx: fix esdhc_change_pinstate() to allow default state restore
esdhc_change_pinstate() checks for pins_100mhz and pins_200mhz at the
top of the function and returns -EINVAL if either is not defined. This
prevents the default case from ever being reached, which means devices
with a sleep pinctrl state but without high-speed pin states (100mhz/
200mhz) can never restore their default pin configuration.
Move the IS_ERR checks for pins_100mhz and pins_200mhz into their
respective switch cases. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-esdhc-imx: use pm_runtime_resume_and_get() in suspend
Replace pm_runtime_get_sync() with pm_runtime_resume_and_get() to
simplify error handling. pm_runtime_resume_and_get() automatically
drops the usage counter on failure, avoiding the need for a separate
pm_runtime_put_noidle() call. If it fails, the device is unclocked and
accessing hardware registers would cause a kernel panic, so return the
error immediately. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Reject negative const offsets for buffer pointers
The verifier rejects variable offsets for PTR_TO_TP_BUFFER and PTR_TO_BUF
accesses, but it currently accepts a constant negative offset produced by
pointer arithmetic.
Commit 022ac0750883 ("bpf: use reg->var_off instead of reg->off for
pointers") moved constant pointer offsets from reg->off to reg->var_off.
However, __check_buffer_access() continued to check only the instruction
offset. An access with reg->var_off equal to -8 and an instruction offset
of zero therefore passes verification.
For writable raw tracepoints, the access end is also calculated from the
unsigned reg->var_off.value. An eight-byte access starting at -8 wraps
the calculated end to zero, allowing the program to load and attach
without increasing max_tp_access.
After ensuring that reg->var_off is constant, calculate the effective
access start using signed arithmetic and reject it when it is negative.
Use the validated start to calculate the access end for both
PTR_TO_TP_BUFFER and PTR_TO_BUF. |

| The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to generic SQL Injection via the 'tag_query' parameter in all versions up to, and including, 4.5.14 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with vendor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the attacker to trigger the vulnerable Legacy_Contact_Query code path by submitting an unknown filter type (e.g. filters[0][0][type]=force_fallback), which causes a FilterException that dispatches execution away from the modern query handler. |
