EUVD-2026-59249

In the Linux kernel, the following vulnerability has been resolved: netfilter: xtu32: reject invalid shift counts u32matchit executes rule-supplied shift operands on a 32-bit value. A malformed u32 rule can provide a shift count of 32 or more, triggering an undefined shift out-of-bounds during...

CVE-2026-64414

CVE-2026-64414 : In the Linux kernel, the netfilter path handling unreadable fragments has been resolved. The issue arises when an skb with unreadable fragments (eg, from devmem TCP) is processed by the u32 module, causing skb_copy_bits() to return a negative error code. Mitigations described acr...

CVE-2023-39192

A flaw was found in the Netfilter subsystem in the Linux kernel. The xtu32 module did not validate the fields in the xtu32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds read by setting the size fields with a value beyond the array boundaries, leading to a cra...
