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: xsk: fix NULL pointer dereference in
 __xsk_rcv() In the __xsk_rcv() multi-buffer path, xsk_buff_alloc() is called in a loop without checking
 its return value. xsk_buff_can_alloc() only counts fill queue entries without validating their addresses,
 so it can succeed while xsk_buff_alloc() rejects all remaining entries and returns NULL. Oops: general
 protection fault, probably for non-canonical address 0xdffffc0000000000 KASAN: null-ptr-deref in range
 [0x0000000000000000-0x0000000000000007] RIP: 0010:__xsk_rcv+0x426/0xc20 (net/xdp/xsk.c:350) Call Trace:
 xsk_generic_rcv+0x26d/0x5f0 xdp_do_generic_redirect+0x3c5/0xcf0 do_xdp_generic+0x92f/0xe70
 __netif_receive_skb_core.constprop.0+0xf7e/0x2b30 Fix this with a two-stage transaction. First allocate
 and stage all buffers required for the packet, recycling all staged buffers with xsk_buff_free() if any
 allocation fails. Only after this stage succeeds, copy the data, reserve the RX descriptors, and release
 the buffers in an error-free loop. (CVE-2026-90115)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
