In the Linux kernel, the following vulnerability has been resolved: i2c: piix4: Fix a memory leak in the EFCH MMIO support The recently added support for EFCH MMIO regions introduced a memory leak in that code path. The leak is caused by the fact that release_resource() merely removes the resource from the tree but does not free its memory. We need to call release_mem_region() instead, which does free the memory. As a nice side effect, this brings back some symmetry between the legacy and MMIO paths.

  - In the Linux kernel, the following vulnerability has been resolved: af_unix: Fix a data-race in     unix_dgram_peer_wake_me(). unix_dgram_poll() calls unix_dgram_peer_wake_me() without `other`'s lock held     and check if its receive queue is full. Here we need to use unix_recvq_full_lockless() instead of     unix_recvq_full(), otherwise KCSAN will report a data-race. (CVE-2022-49344)

  - In the Linux kernel, the following vulnerability has been resolved: x86/MCE/AMD: Fix memory leak when     threshold_create_bank() fails In mce_threshold_create_device(), if threshold_create_bank() fails, the     previously allocated threshold banks array @bp will be leaked because the call to     mce_threshold_remove_device() will not free it. This happens because mce_threshold_remove_device() fetches     the pointer through the threshold_banks per-CPU variable but bp is written there only after the bank     creation is successful, and not before, when threshold_create_bank() fails. Add a helper which unwinds all     the bank creation work previously done and pass into it the previously allocated threshold banks array for     freeing. [ bp: Massage. ] (CVE-2022-49549)
