In the Linux kernel, the following vulnerability has been resolved: netsched: clsflow: validate TCAFLOWRSHIFT attribute The syzbot found that the TCAFLOWRSHIFT attribute was not validated. Shifting a 32-bit integer is undefined for large shift values. UBSAN: Shift-out-of-bounds in...

CVE-2026-64006

A flaw was found in the Linux kernel's Netfilter nftables component. This vulnerability occurs during lshift and rshift operations when the source and destination registers point to the same memory location. An incorrect calculation of the carry value, using the modified destination instead of th...

CVE-2026-64006: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: fix dst corruption in same register operation For lshift and rshift, the shift operations are performed in a loop over 32-bit words. The loop calculates the shifted value and write it to dst, and then...
