SUSE CVE-2026-46101

In the Linux kernel, the following vulnerability has been resolved: netfilter: reject zero shift in nftbitwise Reject zero shift operands for nftbitwise left and right shift expressions during initialization. The carry propagation logic computes the carry from the adjacent 32-bit word using...

CVE-2026-46101

A flaw was found in the Linux kernel's Netfilter subsystem. Specifically, the nftbitwise expression incorrectly handles zero shift operands during initialization. This can lead to undefined behavior within the kernel, potentially causing system instability. An attacker could exploit this by...

CVE-2026-46101

CVE-2026-46101 — Linux kernel netfilter nft_bitwise : The issue arises in the carry-propagation for 32-bit words when a zero shift operand is used in nft_bitwise left/right shift expressions, causing undefined behaviour. The fix rejects zero shift operands during initialization and extends the ex...
