CVE-2026-53062 dm cache policy smq: fix missing locks in invalidating cache blocks

In the Linux kernel, the following vulnerability has been resolved: dm cache policy smq: fix missing locks in invalidating cache blocks In passthrough mode, the policy invalidatemapping operation is called simultaneously from multiple workers, thus it should be protected by a lock. Otherwise, we...

CVE-2026-53060

CVE-2026-53060 is a Linux kernel memory-leak in dm_cache_metadata_abort when a root_lock can’t be acquired due to a read-only metadata state. The issue is fixed in updated kernels (e.g., Root’s rootio-linux patches for Ubuntu 22.04/24.04 and related distro advisories). Affected environments shoul...

In the Linux kernel, the following vulnerability has been resolved: dm log: fix out-of-bounds write due to regioncount overflow The local variable regioncount in createlogcontext is declared as unsigned int 32-bit, but dmsectordivup returns sectort 64-bit. When a device-mapper target has a...

CVE-2026-53059

The CVE-2026-53059 issue is a Linux kernel dm-log out-of-bounds write caused by an unsigned 32-bit region_count in create_log_context() overflowing when dm_sector_div_up() returns a 64-bit value. Large region_space can truncate bitset_size, causing clean_bits, sync_bits, and recovering_bits to be...
