CVE-2026-52986

The CVE-2026-52986 issue affects the Linux kernel netfilter nf_conntrack_sip module, where unsafe port parsing on non-NUL-terminated data allowed malformed SIP packets to affect conntrack processing. The fix introduces a dedicated sip_parse_port() that validates each digit against the buffer limi...

CVE-2026-52921

A flaw was found in the Linux kernel's netfilter ipset component. Specifically, certain hash set variants such as hash:ip,mark and hash:ip,port that iterate IPv4 ranges with a 32-bit iterator do not correctly stop at the end of the requested range. This can cause the iteration to advance beyond t...

UBUNTU-CVE-2026-52923

In the Linux kernel, the following vulnerability has been resolved: ipc: limit nextid allocation to the valid ID range The checkpoint/restore sysctl path can request the next SysV IPC id through ids-nextid. ipcidralloc currently forwards that request to idralloc with an open-ended upper bound. If...

CVE-2026-52923

The CVE-2026-52923 issue affects the Linux kernel IPC ID allocation in the checkpoint/restore path. ipc_idr_alloc() forwards the next_id request to idr_alloc() with an open-ended upper bound, so if the valid SysV IPC id tail is full the allocation can spill past ipc_mni. The encoded id may then r...

CVE-2026-52921

CVE-2026-52921 : In the Linux kernel, netfilter ipset hash:* range iteration could continue past the upper bound when iterating IPv4 ranges, due to a 32-bit iterator not stopping at the end. This allowed traversal state to move past the requested boundary and potentially affect retries. The issue...
