[USN-6234-1] Linux kernel (Xilinx ZynqMP) vulnerability

Severity High
Affected Packages 11
CVEs 1
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

Hangyu Hua discovered that the Flower classifier implementation in the
Linux kernel contained an out-of-bounds write vulnerability. An attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2023-35788, LP: #2023577)

It was discovered that for some Intel processors the INVLPG instruction
implementation did not properly flush global TLB entries when PCIDs are
enabled. An attacker could use this to expose sensitive information
(kernel memory) or possibly cause undesired behaviors. (LP: #2023220)
