Details

Nick Gregory discovered that the Linux kernel incorrectly handled network
offload functionality. A local attacker could use this to cause a denial of
service or possibly execute arbitrary code. (CVE-2022-25636)

Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano
Giuffrida discovered that hardware mitigations added by ARM to their
processors to address Spectre-BTI were insufficient. A local attacker could
potentially use this to expose sensitive information. (CVE-2022-23960)

Max Kellermann discovered that the Linux kernel incorrectly handled Unix
pipes. A local attacker could potentially use this to modify any file that
could be opened for reading. (CVE-2022-0847)

Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano
Giuffrida discovered that hardware mitigations added by Intel to their
processors to address Spectre-BTI were insufficient. A local attacker could
potentially use this to expose sensitive information. (CVE-2022-0001,
CVE-2022-0002)
