0 CVE-2026-13215 is a vulnerability in the Zephyr ext2 filesystem driver where the s_log_block_size field from the on-disk superblock is not properly validated during filesystem mount. This allows an attacker to supply a crafted ext2 image with a manipulated s_log_block_size value that can cause an out-of-bounds write in kernel memory. The flaw arises because the driver calculates a block size based on this unchecked field and uses it to initialize memory slabs without verifying buffer boundaries. This can lead to memory corruption with impacts ranging from denial of service to potential code execution in kernel mode.
