Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: gpio: pca953x: Fixed the race condition in pca953xirqbussyncunlock. Ensure that i2clock is held when setting the interrupt latch and mask in pca953xirqBusSyncUnlock. This prevents race conditions. Another non-probing call site...

CVE-2026-74733

A flaw was found in the Linux kernel's gpio: pca953x driver, which manages General Purpose Input/Output GPIO expanders. The driver uses its own locking mechanism, but the pca953xirqbussyncunlock function failed to acquire the necessary lock when performing register operations. This oversight coul...
