CVE-2020-25285

CVE-2020-25285 is a race condition in the Linux kernel hugetlb sysctl handlers (mm/hugetlb.c) that could allow a local attacker to corrupt memory or trigger NULL pointer dereferences. Public docs (e.g., ChangeLog-5.8.8) indicate the fix was released in kernel 5.8.8; Ubuntu/Debian advisories refer...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the priotree handling of the hugetlb support that allowed a local user to cause a denial of service. This only affected kernels with hugetlb support...

kernel: userfaultfd bypasses tmpfs file permissions

A flaw was found in the Linux kernel with files on tmpfs and hugetlbfs. An attacker is able to bypass file permissions on filesystems mounted with tmpfs/hugetlbs to modify a file and possibly disrupt normal system behavior. At this time there is an understanding there is no crash or privilege...
