2024-05-23: CVE-2024-26923 was added to this advisory.
In the Linux kernel, the following vulnerability has been resolved:
nfsd: fix RELEASE_LOCKOWNER (CVE-2024-26629)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: disallow anonymous set with timeout flag (CVE-2024-26642)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout (CVE-2024-26643)
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix garbage collector racing against connect() (CVE-2024-26923)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path
The commit mutex should not be released during the critical sectionbetween nft_gc_seq_begin() and nft_gc_seq_end(), otherwise, async GCworker could collect expired objects and get the released commit lockwithin the same GC sequence.
nf_tables_module_autoload() temporarily releases the mutex to loadmodule dependencies, then it goes back to replay the transaction again.Move it at the end of the abort phase after nft_gc_seq_end() is called.
(CVE-2024-26925)
In the Linux kernel, the following vulnerability has been resolved:
PCI/PM: Drain runtime-idle callbacks before driver removal (CVE-2024-35809)
In the Linux kernel, the following vulnerability has been resolved:
ACPI: CPPC: Use access_width over bit_width for system memory accesses (CVE-2024-35995)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
