A vulnerability in the Linux kernel's ext4 filesystem code allows an out-of-bounds read due to an improper bounds check in the check_xattrs() function. The issue arises because the bounds check permits a pointer to be within sizeof(u32) bytes of the end of the valid region, leading to a 4-byte read beyond the valid memory area. This can cause a high-severity impact including potential denial of service due to memory corruption. The vulnerability affects version 3.0 of the Linux kernel ext4 code as specified. A fix involves adjusting the bounds check to ensure sufficient space for the 4-byte read. No patch link is provided in the data, and no known exploits are reported in the wild.
