high Tenable Cloud Security Plugin ID 472630

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: virtio-net: fix received length check
in big packets Since commit 4959aebba8c0 ("virtio-net: use mtu size as buffer length for big packets"),
when guest gso is off, the allocated size for big packets is not MAX_SKB_FRAGS * PAGE_SIZE anymore but
depends on negotiated MTU. The number of allocated frags for big packets is stored in
vi->big_packets_num_skbfrags. Because the host announced buffer length can be malicious (e.g. the host
vhost_net driver's get_rx_bufs is modified to announce incorrect length), we need a check in virtio_net
receive path. Currently, the check is not adapted to the new change which can lead to NULL page pointer
dereference in the below while loop when receiving length that is larger than the allocated one. This
commit fixes the received length check corresponding to the new change. (CVE-2025-40292)

Solution

Update the sys-kernel/csql-kernel-6_12 library and its related packages to version 19216.104.72 or later.
