CVE-2023-52735

The CVE-2023-52735 entry concerns a Linux kernel vulnerability in bpf/sockmap where sock_map_{close,destroy,unhash} could call themselves, risking a recursive loop and potential stack overflow. The design should prevent sock_map proto callbacks from calling themselves; the fix breaks recursive ca...

CVE-2023-52735 bpf, sockmap: Don't let sock_map_{close,destroy,unhash} call itself

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Don't let sockmapclose,destroy,unhash call itself sockmap proto callbacks should never call themselves by design. Protect against bugs like 1 and break out of the recursive loop to avoid a stack overflow in favor of...

CVE-2021-47298

CVE-2021-47298 concerns the Linux kernel: a bpf/sockmap path could leak a message if skb_linearize fails, resolved by freeing the msg block before returning an error. Multiple connected advisories reference the same fix in the kernel; impact is a potential memory leak (no exploitation details pro...

CVE-2024-35895

CVE-2024-35895 addresses a vulnerability in the Linux kernel's Berkeley Packet Filter BPF subsystem, specifically within the sockmap feature. The issue arises when BPF tracing programs, which can execute in various interrupt contexts, attempt to delete elements from sockmap or sockhash maps. This...

CVE-2024-35895

The CVE-2024-35895 vulnerability affects the Linux kernel, specifically the BPF sockmap/sockhash path. A deadlock could occur when map_delete_elem is invoked from a context where interrupts are disabled; the fix adds a hardirq-safety check to bail out if map_delete_elem runs in a non-hardirq-unsa...
