CVE-2024-46858

CVE-2024-46858 in the Linux kernel fixes a local UAF race in mptcp_pm_del_add_timer. Two paths can access mptcp_pm_del_add_timer concurrently (CPU1 in PM code path vs CPU2 in netlink/ip stack path), leading to use-after-free when a timer entry is freed after leaving the critical region. The patch...

CVE-2024-46845

CVE-2024-46845 (Linux kernel): The timerlat use-after-free occurs when a SIGTERM kills user-space tracing threads, causing an hrtimer to be freed twice during thread shutdown. The documented fix cancels the hrtimer only if the associated thread still exists and adds an interface_lock around tlat_...

CVE-2024-46845 tracing/timerlat: Only clear timer if a kthread exists

In the Linux kernel, the following vulnerability has been resolved: tracing/timerlat: Only clear timer if a kthread exists The timerlat tracer can use user space threads to check for osnoise and timer latency. If the program using this is killed via a SIGTERM, the threads are shutdown one at a ti...

kernel: tcp: avoid too many retransmit packets

A vulnerability was found in the tcpretransmittimer function in the Linux kernel's TCP implementation. This issue occurs when a TCP socket uses TCPUSERTIMEOUT and the peer's window retracts to zero, leading to excessive retransmission of packets every two milliseconds for up to four minutes after...

kernel: watchdog: Fix possible use-after-free by calling del_timer_sync()

A vulnerability was found in the deltimer function in the Linux kernel's watchdog driver. This issue occurs because the function does not wait for the timer handler to finish, which may lead to a situation where the handler runs after the driver that has been removed, causing a use-after-free iss...

kernel: mISDN: fix possible use-after-free in HFC_cleanup()

A vulnerability was found in the Linux kernel's mISDN driver. This issue arises during the cleanup process, where a timer handler might still be running after the driver has been removed, which can lead to a use-after-free issue, potentially causing a system crash...

kernel: x86: stop playing stack games in profile_pc()

In the Linux kernel, the following vulnerability has been resolved: x86: stop playing stack games in profilepc The 'profilepc' function is used for timer-based profiling, which isn't really all that relevant any more to begin with, but it also ends up making assumptions based on the stack layout...
