In the Linux kernel, the following vulnerability has been resolved: security/keys: fix missed RCU read section on lookup Nicholas Carlini reports that the keyring co...

SUSE CVE-2026-68374

In the Linux kernel, the following vulnerability has been resolved: usb: core: sysfs: add lock to bosdescriptorsread Add a lock to the function bosdescriptorsread. This function accesses udev-bos, which could be simultaneously freed in usbresetandverifydevice, a function that is commonly called i...

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...

CVE-2026-74646

A flaw was found in the Linux kernel's fastrpc subsystem. When an invoke operation is interrupted by a signal, the fastrpcinternalinvoke function moves memory mappings without properly holding the fl-lock. This missing lock during memory map manipulation creates a race condition, which could lead...
