CVE-2026-43319

A flaw was found in the Linux kernel's spidev driver. A local user, by performing concurrent write and ioctl operations on the same spidev file descriptor from separate threads, could trigger a lock inversion. This issue can lead to a deadlock, resulting in a Denial of Service DoS for the affecte...

In the Linux kernel, the following vulnerability has been resolved: btrfs: reserve enough transaction items for qgroup ioctls Currently our qgroup ioctls don't reserve any space, they just do a transaction join, which does not reserve any space, neither for the quota tree updates nor for the...

CVE-2026-43338

CVE-2026-43338 affects the Linux kernel with the Btrfs filesystem. The issue arises because qgroup ioctls do not reserve transaction space, allowing -ENOSPC scenarios during quota-tree updates and delayed refs, which can abort transactions and enable a DoS condition. Vendors have published adviso...
