CVE-2026-64024

A flaw was found in the Linux kernel's Transmission Control Protocol TCP networking stack. This vulnerability arises from a stale per-CPU variable that can retain a previously used Initial Sequence Number ISN when certain packets are dropped. A remote attacker could exploit this by sending...

SUSE CVE-2026-64024

In the Linux kernel, the following vulnerability has been resolved: tcp: fix stale per-CPU tcptwisn leak enabling ISN prediction Blamed commit moved the TIMEWAIT-derived ISN from the skb control block to a per-CPU variable, assuming the value would always be consumed by tcpconnrequest for the sam...

CVE-2026-63799

A flaw was found in the Linux kernel's scheduler component. A local attacker could exploit an out-of-bounds write vulnerability during the creation or execution of a new task in per-CPU mode, specifically when an internal identifier is unassigned. This can lead to a bounded memory corruption, whe...

CVE-2026-63799

CVE-2026-63799: Linux kernel fix for an OOB clear_bit in per-CPU CID handling. If a task runs with mm_cid.cid == MM_CID_UNSET during fixup (lazy CID assignment), cid_in_transit() can convert it to MM_CID_UNSET | MM_CID_TRANSIT. Later mm_cid_schedout() can clear_bit() using MM_CID_UNSET as the bit...
