CVE-2024-26925

CVE-2024-26925 affects the Linux kernel netfilter nf_tables module. The root cause is releasing the commit mutex during the critical section between nft_gc_seq_begin() and nft_gc_seq_end(), which allows an async GC worker to collect expired objects and acquire the released commit lock within the ...

Ubuntu 20.04 LTS / 22.04 LTS : Linux kernel vulnerabilities (USN-6742-1)

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6742-1 advisory. Daniele Antonioli discovered that the Secure Simple Pairing and Secure Connections pairing in the Bluetooth protocol could allow an...

CVE-2024-26780

A flaw was found in the Linux kernel's afunix subsystem where tasks could hang while purging out-of-bounds sockets during garbage collection. This issue could potentially lead to system instability. Mitigation Mitigation for this issue is either not available or the currently available options do...

CVE-2024-26780

CVE-2024-26780 | Linux kernel (af_unix) — The vulnerability centers on a task hang during purging oob_skb in GC. The root cause is that list_for_each_entry_safe() is not actually safe when a single skb has references from multiple sockets; freeing such an skb can unlink current and next sockets i...

CVE-2024-26676

CVE-2024-26676 concerns the Linux kernel’s af_unix garbage collection. The issue arose when a socketpair self-send creates a self-referential GC candidate cycle that is not untangled due to missing MSG_OOB handling, causing a memory leak. The root cause was exposed after removing io_uring GC dead...
