CVE-2022-49879

CVE-2022-49879 affects the Linux kernel ext4 code. A corrupted directory entry where rec_len is invalid (not a multiple of 4) can cause a kernel BUG() in ext4_rec_len_to_disk() called from make_indexed_dir(). The fix adds a validation step via ext4_check_dir_entry(), returning -EFSCORRUPTED for i...

CVE-2022-49878

Summary: CVE-2022-49878 is a Linux kernel vulnerability in the bpf verifier’s array reallocation. When realloc_array() errors (krealloc() returns NULL), callers previously set their pointers to NULL, but krealloc() leaves the original allocation untouched, causing a memory leak. The description i...
