CVE-2026-52928: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: afunix: Reject SIOCATMARK on non-stream sockets SIOCATMARK reports whether the receive queue is at the urgent mark for MSGOOB. In AFUNIX, MSGOOB is supported only for SOCKSTREAM sockets. SOCKDGRAM and SOCKSEQPACKET reject MSGOOB ...

SUSE CVE-2026-45887

In the Linux kernel, the following vulnerability has been resolved: afunix: Fix memleak of newsk in unixstreamconnect. When preparepeercred fails in unixstreamconnect, unixreleasesock is not called for newsk, and the memory is leaked. Let's move preparepeercred before unixcreate1...

CVE-2026-45887

A flaw was found in the Linux kernel's afunix subsystem. This vulnerability, a memory leak, occurs in the unixstreamconnect function when a specific internal operation fails to release allocated memory. Over time, this unreleased memory could accumulate, potentially leading to system instability ...

CVE-2026-45887

CVE-2026-45887 affects the Linux kernel af_unix subsystem's unix_stream_connect() path. Root cause: if prepare_peercred() fails, unix_release_sock() is not called for the new socket (newsk), causing a memory leak. Impact: potential DoS or instability due to unreleased memory. Remediation: move pr...
