Описание
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()]
A vulnerability was found in the afs_update_volume_status() function in the Linux kernel. This issue could lead to a buffer overflow due to an improperly sized char array that is not large enough to match the corresponding value being placed in it, leading to memory corruption or crashes.
Отчет
Red Hat Enterprise Linux 8 and 9 are not affected by this vulnerability.
