Summary
In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - fix race condition in reset_device sysfs callback The ims_pcu_reset_device() sysfs callback calls ims_pcu_execute_command() without acquiring pcu->cmd_mutex.
This can lead to data races and corruption of the shared command buffer if triggered concurrently with other commands. Acquire pcu->cmd_mutex before calling ims_pcu_execute_command().
A race condition occurs when the `ims_pcu_reset_device()` function is called without proper synchronization, allowing concurrent operations to corrupt a shared command buffer. This vulnerability could be exploited by a local attacker to cause system instability or a denial of service.
Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-414.
Red Hat lists Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected.
