CVE-2026-98102

The Linux kernel contains a vulnerability in the ipv6 multicast implementation within the ip6_mc_del1_src() function. When a source filter's count reaches zero, the code incorrectly moves the filter directly into the tombstone list by mutating psf->sf_next before an RCU grace period elapses. B...

CVE-2026-98101

The Linux kernel contains a vulnerability in the ipv6 multicast implementation where the pmc->sflist is read locklessly under rcu_read_lock() by inet6_mc_check() during packet reception in UDP and RAW multicast receive paths. The root cause is that ip6_mc_source() performs in-place mutation of...

CVE-2026-98038

The Linux kernel contains a vulnerability in the BPF subsystem where bpf_refcount_acquire() incorrectly treats certain borrowed RCU kptrs as owning references. Specifically, refcounted objects without a graph node appear as owning references even without an acquired state. This allows a program t...
