kernel: perf: Fix event leak upon exec and file release

Linux kernel perf pending task work is never waited upon the matching event release; in the case of a child event, released via freeevent directly, this can potentially result in a leaked event...

kernel: dmaengine: idxd: Avoid unnecessary destruction of file_ida

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Avoid unnecessary destruction of fileida fileida is allocated during cdev open and is freed accordingly during cdev release. This sequence is guaranteed by driver file operations. Therefore, there is no need to...

kernel: fbdev: Fix invalid page access after closing deferred I/O devices

In the Linux kernel, the following vulnerability has been resolved: fbdev: Fix invalid page access after closing deferred I/O devices When a fbdev with deferred I/O is once opened and closed, the dirty pages still remain queued in the pageref list, and eventually later those may be processed in t...

kernel: PM / devfreq: Synchronize devfreq_monitor_[start/stop]

A flaw was found in the Linux kernel resulting from race conditions and a lack of synchronization in handling the delayed work timers in the devfreq component. This issue can lead to inconsistencies and a corruption of the timer list...

kernel: net/mlx5e: SHAMPO, Fix invalid WQ linked list unlink

In Linux kernel net/mlx5e, for SHAMPO, it is possible to receive CQEs with 0 consumed strides for the same WQE even after the WQE is fully consumed and unlinked. This triggers an additional unlink for the same wqe which corrupts the linked list...

kernel: perf: Fix event leak upon exit

A logical flaw exists in the Linux kernel. When a task is scheduled, pending sigtrap deliveries are deferred to the target task upon resuming to userspace via taskwork. However, failures are ignored while adding an event's callback to the taskwork engine. Since the last call for the event exit...

kernel: Input: gpio-keys - cancel delayed work only in case of GPIO

In the Linux kernel, the following vulnerability has been resolved: Input: gpio-keys - cancel delayed work only in case of GPIO gpiokeys module can either accept gpios or interrupts. The module initializes delayed work in case of gpios only and is only used if debounce timer is not used, so make...
