CVE-2023-53395

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.0.0-dev-th500-6.0.y-1+bcf8c46459e407-generic-64k

Description The Linux kernel contains a flaw within the ACPICA component related to the handling of ASL Timer instructions. Specifically, the issue arises when interpreting ASL timer instructions by the ACPI interpreter, leading to an error. The addition of the AML NO OPERAND RESOLVE flag to the ASL Timer instruction opcode resolves this issue. Additionally, a use-after-free condition was identified in acpica/dswexec.c resulting in an out-of-bounds array access.

Recommendations Update to Linux kernel version 6.0.0-dev-th500-6.0.y-1+bcf8c46459e407-generic-64k or later.
