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 relates to the Linux kernel netfilter component, specifically the nft_bitwise operation. The issue arises from zero shift operands in left/right shift expressions during initialization. The carry propagation logic uses BITS_PER_TYPE(u32) - shift; a zero shift operand can produce a ...
