CVE-2023-54268 debugobjects: Don't wake up kswapd from fill_pool()

In the Linux kernel, the following vulnerability has been resolved: debugobjects: Don't wake up kswapd from fillpool syzbot is reporting a lockdep warning in fillpool because the allocation from debugobjects is using GFPATOMIC, which is GFPHIGH | GFPKSWAPDRECLAIM and therefore tries to wake up...

CVE-2023-54268

The CVE-2023-54268 entry concerns a Linux kernel fix for debugobjects: avoid waking kswapd from fill_pool() when GFP_ATOMIC allocations trigger kswapd_wait::lock. The root cause is using GFP_ATOMIC (effectively GFP_HIGH | GFP_KSWAPD_RECLAIM), which can wake up kswapd during fill_pool() as it may ...

Linux kernel 安全漏洞

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 improper use of the GFP flag for fillpool in debugobjects, which could lead to a deadlock...

CVE-2024-53128

In the Linux kernel, the following vulnerability has been resolved: sched/taskstack: fix objectisonstack for KASAN tagged pointers When CONFIGKASANSWTAGS and CONFIGKASANSTACK are enabled, the objectisonstack function may produce incorrect results due to the presence of tags in the obj pointer,...

kernel: debugobjects: Don't wake up kswapd from fill_pool()

A locking issue was found in the Linux kernel's debugobjects subsystem. The fillpool function uses GFPATOMIC allocation flags, which attempt to wake up kswapd and acquire kswapdwait::lock. Since fillpool may be called with arbitrary locks already held, this can trigger lockdep warnings about...

CVE-2021-47419 net/sched: sch_taprio: properly cancel timer from taprio_destroy()

In the Linux kernel, the following vulnerability has been resolved: net/sched: schtaprio: properly cancel timer from tapriodestroy There is a comment in qdisccreate about us not calling ops-reset in some cases. errout4: / Any broken qdiscs that would require a ops-reset here? The qdisc was never ...

CVE-2021-47387

In the Linux kernel, the following vulnerability has been resolved: cpufreq: schedutil: Use kobject release method to free sugovtunables The struct sugovtunables is protected by the kobject, so we can't free it directly. Otherwise we would get a call trace like this: ODEBUG: free active active...

CVE-2024-26681 netdevsim: avoid potential loop in nsim_dev_trap_report_work()

In the Linux kernel, the following vulnerability has been resolved: netdevsim: avoid potential loop in nsimdevtrapreportwork Many syzbot reports include the following trace 1 If nsimdevtrapreportwork can not grab the mutex, it should rearm itself at least one jiffie later. 1 Sending NMI from CPU ...
