UBUNTU-CVE-2026-53219

In the Linux kernel, the following vulnerability has been resolved: netfilter: xtables: avoid leaking percpu counter pointers The native and compat get-entries paths copy the fixed rule entry header from the kernelized rule blob to userspace before overwriting the entry's counter fields with a...

CVE-2026-53266

The CVE-2026-53266 entry concerns the Linux kernel netfilter bridge path, where ebt_snat ARP sender hardware address rewrite could be performed on non-writable memory. Root cause: ARP SHA is written via skb_store_bits() relative to skb->data, and skb_header_pointer() only safely reads the ARP ...

CVE-2026-53228

The CVE-2026-53228 entry documents a vulnerability in the Linux kernel SIT IPv6 tunnel driver. When GSO offloads are used, the code may keep a stale pointer to the inner IPv6 header after skb header unclone and potential headroom reallocation, leading to reads from freed memory. A fix reloads the...
