Name of the Vulnerable Software and Affected Versions
Linux kernel version 5.10.246-syzkaller
Description
A NULL pointer dereference occurs in the
afs get tree() function. This happens because afs alloc sbi() utilizes kzalloc for memory allocation; when ctx->dyn root is not null, the as->cell and as->volume variables remain null. These null variables are subsequently dereferenced within the trace afs get tree() function.Recommendations
Update the Linux kernel to a version where the
afs get tree() NULL pointer dereference has been resolved.Exploit
