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...
