CVE-2026-45842 slip: reject VJ receive packets on instances with no rstate array
In the Linux kernel, the following vulnerability has been resolved: slip: reject VJ receive packets on instances with no rstate array slhcinit accepts rslots == 0 as a valid configuration, with the documented meaning of 'no receive compression'. In that case the allocation loop in slhcinit is...
CVE-2026-45841 netfilter: nfnetlink_osf: fix divide-by-zero in OSF_WSS_MODULO
In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinkosf: fix divide-by-zero in OSFWSSMODULO nfosfmatchone computes ctx-window % f-wss.val in the OSFWSSMODULO branch with no guard for f-wss.val == 0. A CAPNETADMIN user can add such a fingerprint via nfnetlink; a...

CVE-2026-45841
The CVE concerns the Linux kernel, specifically netfilter nfnetlink_osf and the OSF_WSS_MODULO path. Root cause: nf_osf_match_one() can perform ctx->window % f->wss.val without guarding f->wss.val == 0, enabling a CAP_NET_ADMIN user to inject a bogus fingerprint via nfnetlink, leading to...

CVE-2026-45838
The CVE-2026-45838 entry concerns the Linux kernel BPF code: the function cgroup_storage_get_next_key() incorrectly handled end-of-list detection because list_next_entry() could wrap to the list head, making the subsequent NULL check dead code and causing -ENOENT not to be returned for the last e...

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix use-after-free in arenavmclose on fork arenavmopen only bumps vml-mmapcount but never registers the child VMA in arena-vmalist. The vml-vma always points at the parent VMA, so after parent munmap the pointer dangles. If...
kernel: Linux kernel: Use-after-free in bonding driver leads to denial of service
A flaw was found in the Linux kernel's bonding driver. A local attacker with low privileges could exploit a use-after-free vulnerability in the bondxmitbroadcast function. This occurs due to a race condition during concurrent slave enslave/release operations, which can lead to the original socket...
kernel: Linux kernel: Use-after-free in traffic control (act_ct) may lead to denial of service or privilege escalation
A flaw was found in the Linux kernel. A use-after-free vulnerability exists in the traffic control actct path when it is incorrectly configured with non-ingress egress qdiscs queueing disciplines. This can allow a local user with specific privileges to trigger a kernel crash, leading to a denial ...
kernel: md/bitmap: fix GPF in write_page caused by resize race
A flaw was found in the Linux kernel's md/bitmap component. This vulnerability involves a use-after-free race condition that occurs during array resize operations. When the bitmapdaemonwork and bitmapresize functions execute concurrently, they can access memory pages that have already been freed...
kernel: Linux kernel: Denial of service and memory corruption in RDMA umad
A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA umad User Mode Access Device component. A local user can exploit this vulnerability by manipulating input, causing an integer underflow that leads to an out-of-bounds memory write. This memory corruption can result in a denia...
