kernel: sched/psi: Fix use-after-free in ep_remove_wait_queue()

In the Linux kernel, the following vulnerability has been resolved: sched/psi: Fix use-after-free in epremovewaitqueue If a non-root cgroup gets removed when there is a thread that registered trigger and is polling on a pressure file within the cgroup, the polling waitqueue gets freed in the...

kernel: tty: n_gsm: fix possible out-of-bounds in gsm0_receive()

A vulnerability was found in the Linux kernel's ngsm driver, affecting the tty subsystem. It occurs when switching between basic and advanced option modes in GSM multiplexing, leading to potential out-of-bounds memory writes. This happens because certain state variables, like gsm-len and gsm-stat...

kernel: pwm: Fix double shift bug

REJECTED CVE A double shift vulnerability was identified in the Linux kernel's pwm subsystem. The issue involves passing a shifted value instead of a bit number to set/testbit functions, resulting in a double shift e.g., BITBIT1. While this doesn't cause problems for values 0 or 1, values of 5 or...
