CVE-2026-31668 seg6: separate dst_cache for input and output paths in seg6 lwtunnel

In the Linux kernel, the following vulnerability has been resolved: seg6: separate dstcache for input and output paths in seg6 lwtunnel The seg6 lwtunnel uses a single dstcache per encap route, shared between seg6inputcore and seg6outputcore. These two paths can perform the post-encap SID lookup ...

CVE-2026-31528

A flaw was found in the Linux kernel's performance monitoring unit PMU subsystem. This vulnerability occurs when handling performance event groups, specifically during the rollback of groupschedin operations. An issue with how inherited contexts use event pointers can lead to an out-of-bounds...

CVE-2026-31457

A flaw was found in the Linux kernel. A local user can exploit this vulnerability by setting the nrcontexts parameter to zero via the DAMON sysfs interface while DAMON Data Access MONitor is active. This improper input validation leads to a NULL pointer dereference, which can cause a system crash...
