Name of the Vulnerable Software and Affected Versions
Linux Kernel (affected versions not specified)
Description
A NULL pointer dereference was found in the
io file bitmap get function in the io uring/filetable.c file of the Linux Kernel. This issue occurs when fixed files are unregistered and some context information, such as file alloc {start,end} and alloc hint, is not cleared. A subsequent request with auto index selection enabled via IORING FILE INDEX ALLOC can cause a NULL pointer dereference, allowing an unprivileged user to cause a system crash.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
