CVE-2023-53222

CVE-2023-53222 pertains to the Linux kernel, specifically the JFS filesystem code (jfs_dmap). The issue is a mounting-time validation flaw in db_l2nbperpage: BLKTODMAP uses db_l2nbperpage to shift, and an unchecked large value can trigger a shift-out-of-bounds crash. The root cause is that db_l2n...
