| CVE-2026-23210 | 1 Linux | 1 Linux Kernel | 2026-04-16 | 4.7 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ice: Fix PTP NULL pointer dereference during VSI rebuild Fix race condition where PTP periodic work runs while VSI is being rebuilt, accessing NULL vsi->rx_rings. The sequence was: 1. ice_ptp_prepare_for_reset() cancels PTP work 2. ice_ptp_rebuild() immediately queues PTP work 3. VSI rebuild happens AFTER ice_ptp_rebuild() 4. PTP work runs and accesses NULL vsi->rx_rings Fix: Keep PTP work cancelled during rebuild, only queue it after VSI rebuild completes in ice_rebuild(). Added ice_ptp_queue_work() helper function to encapsulate the logic for queuing PTP work, ensuring it's only queued when PTP is supported and the state is ICE_PTP_READY.

| CVE-2001-1056 | 1 Linux | 1 Linux Kernel | 2026-04-16 | N/A |
| IRC DCC helper in the ip_masq_irc IP masquerading module 2.2 allows remote attackers to bypass intended firewall restrictions by causing the target system to send a "DCC SEND" request to a malicious server which listens on port 6667, which may cause the module to believe that the traffic is a valid request and allow the connection to the port specified in the DCC SEND request. | ||||
| CVE-2004-0109 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Linux | 2026-04-16 | N/A |
| Buffer overflow in the ISO9660 file system component for Linux kernel 2.4.x, 2.5.x and 2.6.x, allows local users with physical access to overflow kernel memory and execute arbitrary code via a malformed CD containing a long symbolic link entry. | ||||
| CVE-2002-1571 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-04-16 | N/A |
| The linux 2.4 kernel before 2.4.19 assumes that the fninit instruction clears all registers, which could lead to an information leak on processors that do not clear all relevant SSE registers. | ||||
| CVE-2002-0510 | 1 Linux | 1 Linux Kernel | 2026-04-16 | N/A |
| The UDP implementation in Linux 2.4.x kernels keeps the IP Identification field at 0 for all non-fragmented packets, which could allow remote attackers to determine that a target system is running Linux. | ||||

| The sysctl functionality (sysctl.c) in Linux kernel before 2.6.14.1 allows local users to cause a denial of service (kernel oops) and possibly execute code by opening an interface file in /proc/sys/net/ipv4/conf/, waiting until the interface is unregistered, then obtaining and modifying function pointers in memory that was used for the ctl_table. | ||||
| CVE-2005-4635 | 1 Linux | 1 Linux Kernel | 2026-04-16 | N/A |
| The nl_fib_input function in fib_frontend.c in the Linux kernel before 2.6.15 does not check for valid lengths of the header and payload, which allows remote attackers to cause a denial of service (invalid memory reference) via malformed fib_lookup netlink messages. | ||||
