Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: padata: Do not leak the reference count in reorderwork A recent patch that addressed a UAF introduced a reference count leak: The reference count of paralleldata is incremented unconditionally, regardless of the return value of...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: btrfs: Do not call BUGON when the reference count is 0 at btrfslookupextentinfo. Instead of calling BUGON, handle the error by returning -EUCLEAN, aborting the transaction, and logging an error message...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: keys: Fixed UAF in keyput Once a key’s reference count is reduced to 0, the garbage collector thread may destroy it at any time. Therefore, keyput is no longer allowed to access the key after that point. The only action that keyp...

kernel: smb: client: fix TCP timers deadlock after rmmod

REJECTED CVE A vulnerability was suspected in the Linux kernel's SMB client module related to TCP timers and potential deadlocks after module removal rmmod cifs. The issue stemmed from incorrect manual manipulation of sk-sknetrefcnt, which led to TCP timers not being properly cleared, causing...

kernel: amba: bus: fix refcount leak

A reference count leak was found in the ARM AMBA bus driver. When AMBA devices are created from device tree, the ofnode reference count is incremented but never decremented in ambadevicerelease, causing gradual memory leaks...

kernel: sock_map: avoid race between sock_map_close and sk_psock_put

A flaw was found in the Linux kernel's sockmap component. A local attacker could exploit a race condition between the sockmapclose and skpsockput functions. This race condition can lead to a null pointer dereference, which triggers a kernel warning and may result in a denial of service...
