CVE-2023-34256
https://notcve.org/view.php?id=CVE-2023-34256
An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an offset. NOTE: this is disputed by third parties because the kernel is not intended to defend against attackers with the stated "When modifying the block device while it is mounted by the filesystem" access. Se ha descubierto un problema en el kernel de Linux en las versiones anteriores a 6.3.3. Hay una lectura fuera de límites en crc16 en "lib/crc16.c" cuando se llama dese "fs/ext4/super.c" porque "ext4_group_desc_csum" no comprueba correctamente un desplazamiento. • https://bugzilla.suse.com/show_bug.cgi?id=1211895 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.3.3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4f04351888a83e595571de672e0a4a8b74f4fb31 https://lists.debian.org/debian-lts-announce/2023/07/msg00030.html https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://syzkaller.appspot.com/bug?extid=8785e41224a3afd04321 • CWE-125: Out-of-bounds Read •
