Description Dhananjay Arunesh 2020-08-10 03:38:46 UTC

Multiple race conditions in the Advanced Union Filesystem (aufs) aufs3-mmap.patch and aufs4-mmap.patch patches for the Linux kernel allow local users to cause a denial of service (use-after-free and BUG) or possibly gain privileges via a (1) madvise or (2) msync system call, related to mm/madvise.c and mm/msync.c.
