In the Linux kernel, the following vulnerability has been resolved:
efi: libstub: only free priv.runtime_map when allocated
priv.runtime_map is only allocated when efi_novamap is not set.
Otherwise, it is an uninitialized value. In the error path, it is freed
unconditionally. Avoid passing an uninitialized value to free_pool.
Free priv.runtime_map only when it was allocated.

CVE-2024-32936 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Chenyuan Yang discovered that the CEC driver driver in the Linux kernel
contained a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2024-23848)
It was discovered that the JFS file system contained an out-of-bounds read
vulnerability when printing xattr debug information. A local attacker could
use this to cause a denial of service (system crash). (CVE-2024-40902)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- ARM64 architecture;
- MIPS architecture;
- PA-RI
