SUSE CVE-2026-23353

In the Linux kernel, the following vulnerability has been resolved: ice: fix crash in ethtool offline loopback test Since the conversion of ice to page pool, the ethtool loopback test crashes: BUG: kernel NULL pointer dereference, address: 000000000000000c PF: supervisor write access in kernel mo...

CVE-2026-23311

A flaw was found in the Linux kernel's perf/core component. This vulnerability occurs due to an invalid wait context during event scheduling, specifically when a pinned event fails and attempts to wake up threads in the ring buffer. An attacker could potentially exploit this to cause system...
