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...
CVE-2024-46832: Undefined Security Weakness
In the Linux kernel, the following vulnerability has been resolved: MIPS: cevt-r4k: Don't call getc0compareint if timer irq is installed This avoids warning: 0.118053 BUG: sleeping function called from invalid context at kernel/locking/mutex.c:283 Caused by getc0compareint on secondary CPU. We al...

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a failure to properly handle timers when handling timer interrupts. No details of the vulnerability are...
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...
