Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: 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 immediately reads
from src to calculate the carry for the next iteration. Because src and dst could point to the same memory
location, the carry is incorrectly calculated using the newly modified dst value instead of the original
src value. Adding a temporary local variable to cache the original value before writing to dst and using
it for the carry calculation solves the problem. In addition, partial overlap is rejected from control
plane for all kind of operations including byteorder. This was tested with the following bytecode: table
test_table ip flags 0 use 1 handle 1 ip test_table test_chain use 3 type filter hook input prio 0 policy
accept packets 0 bytes 0 flags 1 ip test_table test_chain 2 [ immediate reg 1 0x44332211 0x88776655 ] [
bitwise reg 1 = ( reg 1 << 0x08000000 ) ] [ cmp eq reg 1 0x66443322 0x00887766 ] [ counter pkts 0 bytes 0
] ip test_table test_chain 4 3 [ immediate reg 1 0x44332211 0x88776655 ] [ bitwise reg 1 = ( reg 1 <<
0x08000000 ) ] [ cmp eq reg 1 0x55443322 0x00887766 ] [ counter pkts 21794 bytes 1917798 ]
(CVE-2026-64006)
