https://notcve.org/view.php?id=CVE-2023-52878
In the Linux kernel, the following vulnerability has been resolved: can: dev: can_put_echo_skb(): don't crash kernel if can_priv::echo_skb is accessed out of bounds If the "struct can_priv::echoo_skb" is accessed out of bounds, this would cause a kernel crash. Instead, issue a meaningful warning message and return with an error. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: can: dev: can_put_echo_skb(): no bloquee el kernel si se accede a can_priv::echo_skb fuera de los límites. Si se accede a "struct can_priv::echoo_skb" fuera de los límites, esto provocaría un fallo del kernel. En su lugar, emita un mensaje de advertencia significativo y regrese con un error. • https://git.kernel.org/stable/c/a6e4bc5304033e434fabccabb230b8e9ff55d76f https://git.kernel.org/stable/c/826120c9ba68f2d0dbae58e99013929c883d1444 https://git.kernel.org/stable/c/0d30931f1fa0fb893fb7d5dc32b6b7edfb775be4 https://git.kernel.org/stable/c/53c468008a7c9ca3f5fc985951f35ec2acae85bc https://git.kernel.org/stable/c/8ab67da060157362b2e0926692c659808784708f https://git.kernel.org/stable/c/6411959c10fe917288cbb1038886999148560057 https://access.redhat.com/security/cve/CVE-2023-52878 https://bugzilla.redhat.com/show_bug.cgi?id=2282680 • CWE-125: Out-of-bounds Read •
