Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A race condition was found in the Linux kernel's memory subsystem, related to the copy-on-write (COW) breakage of private read-only shared memory mappings. This issue allows an unprivileged, local user to gain write access to read-only memory mappings, increasing their privileges on the system. The problem is similar to the Dirty COW vulnerability but is limited to affecting data in shared memory (shmem / tmpfs). Exploitation of this issue can be used to modify running executable files that use shared memory.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
