CVE-2023-52436 – f2fs: explicitly null-terminate the xattr list
https://notcve.org/view.php?id=CVE-2023-52436
In the Linux kernel, the following vulnerability has been resolved: f2fs: explicitly null-terminate the xattr list When setting an xattr, explicitly null-terminate the xattr list. This eliminates the fragile assumption that the unused xattr space is always zeroed. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: f2fs: termina explícitamente en nulo la lista xattr Al configurar un xattr, termina explícitamente en nulo la lista xattr. Esto elimina la frágil suposición de que el espacio xattr no utilizado siempre se pone a cero. • https://git.kernel.org/stable/c/16ae3132ff7746894894927c1892493693b89135 https://git.kernel.org/stable/c/12cf91e23b126718a96b914f949f2cdfeadc7b2a https://git.kernel.org/stable/c/3e47740091b05ac8d7836a33afd8646b6863ca52 https://git.kernel.org/stable/c/32a6cfc67675ee96fe107aeed5af9776fec63f11 https://git.kernel.org/stable/c/5de9e9dd1828db9b8b962f7ca42548bd596deb8a https://git.kernel.org/stable/c/2525d1ba225b5c167162fa344013c408e8b4de36 https://git.kernel.org/stable/c/f6c30bfe5a49bc38cae985083a11016800708fea https://git.kernel.org/stable/c/e26b6d39270f5eab0087453d9b544189a •
