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: bpf/bonding: reject vlan+srcmac
 xmit_hash_policy change when XDP is loaded bond_option_mode_set() already rejects mode changes that would
 make a loaded XDP program incompatible via bond_xdp_check(). However, bond_option_xmit_hash_policy_set()
 has no such guard. For 802.3ad and balance-xor modes, bond_xdp_check() returns false when xmit_hash_policy
 is vlan+srcmac, because the 802.1q payload is usually absent due to hardware offload. This means a user
 can: 1. Attach a native XDP program to a bond in 802.3ad/balance-xor mode with a compatible
 xmit_hash_policy (e.g. layer2+3). 2. Change xmit_hash_policy to vlan+srcmac while XDP remains loaded. This
 leaves bond->xdp_prog set but bond_xdp_check() now returning false for the same device. When the bond is
 later destroyed, dev_xdp_uninstall() calls bond_xdp_set(dev, NULL, NULL) to remove the program, which hits
 the bond_xdp_check() guard and returns -EOPNOTSUPP, triggering: WARN_ON(dev_xdp_install(dev, mode, bpf_op,
 NULL, 0, NULL)) Fix this by rejecting xmit_hash_policy changes to vlan+srcmac when an XDP program is
 loaded on a bond in 802.3ad or balance-xor mode. commit 39a0876d595b ("net, bonding: Disallow vlan+srcmac
 with XDP") introduced bond_xdp_check() which returns false for 802.3ad/balance-xor modes when
 xmit_hash_policy is vlan+srcmac. The check was wired into bond_xdp_set() to reject XDP attachment with an
 incompatible policy, but the symmetric path -- preventing xmit_hash_policy from being changed to an
 incompatible value after XDP is already loaded -- was left unguarded in
 bond_option_xmit_hash_policy_set(). Note: commit 094ee6017ea0 ("bonding: check xdp prog when set bond
 mode") later added a similar guard to bond_option_mode_set(), but bond_option_xmit_hash_policy_set()
 remained unprotected. (CVE-2026-23310)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.534.53 or later.
