Posted Oct 14, 2020
Authored by Benjamin M. Romer

It was discovered that the F2FS file system implementation in the Linux kernel did not properly perform bounds checking on xattrs in some situations. A local attacker could possibly use this to expose sensitive information (kernel memory). It was discovered that the Serial CAN interface driver in the Linux kernel did not properly initialize data. A local attacker could use this to expose sensitive information (kernel memory). Other issues where also addressed.

Ubuntu Security Notice 4579-1 - Hador Manor discovered that the DCCP protocol implementation in the Linux kernel improperly handled socket reuse, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Wen Xu discovered that the XFS file system in the Linux kernel did not properly validate inode metadata in some situations. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service. Various other issues were also addressed.
