CVE-2022-49770:
Linux Kernel vulnerability analysis and mitigation
Overview
A vulnerability (CVE-2022-49770) has been identified and resolved in the Linux kernel's Ceph filesystem component. The issue occurs when decoding snaps fails, potentially leaving 'first_realm' and 'realm' pointing to the same snaprealm memory location. This vulnerability was published on May 1, 2025 (NVD, Wiz).
Technical details
The vulnerability exists in the Ceph filesystem component of the Linux kernel. When the decoding of snaps fails, it creates a condition where both 'first_realm' and 'realm' pointers reference the same snaprealm memory location. The subsequent double-put operation on this memory can trigger use-after-free conditions or kernel BUG_ON assertions (Wiz).
Impact
The vulnerability can lead to random use-after-free conditions and kernel BUG_ON assertions, potentially affecting system stability and security. These issues could result in system crashes or potentially allow for unauthorized access to memory (Wiz).
