CVE-2024-26736 – afs: Increase buffer size in afs_update_volume_status()
https://notcve.org/view.php?id=CVE-2024-26736
03 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: afs: Increase buffer size in afs_update_volume_status() The max length of volume->vid value is 20 characters. So increase idbuf[] size up to 24 to avoid overflow. Found by Linux Verification Center (linuxtesting.org) with SVACE. [DH: Actually, it's 20 + NUL, so increase it to 24 and use snprintf()] En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: afs: aumenta el tamaño del búfer en afs_update_volume_status() La longitud má... • https://git.kernel.org/stable/c/d2ddc776a4581d900fc3bdc7803b403daae64d88 •
