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

In the Linux kernel af_unix code, the vulnerability relates to a memleak of the new socket (newsk) in unix_stream_connect(). If prepare_peercred() fails during unix_stream_connect(), unix_release_sock() is not called for the newsk, causing a memory leak. The fix moves prepare_peercred() before un...

In the Linux kernel, the following vulnerability has been resolved: afunix: Fixed a data race in unixdgrampeerwakeme. The unixdgrampoll function calls unixdgrampeerwakeme without ensuring that the other lock is held, and without checking whether its receive queue is full. In this case, we need to...
