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: nvme-pci: fix out-of-bounds access in
nvme_setup_descriptor_pools nvme_setup_descriptor_pools() indexes dev->descriptor_pools[] using the
numa_node forwarded from hctx->numa_node by its single caller, nvme_init_hctx_common(). On a non-NUMA
kernel hctx->numa_node is NUMA_NO_NODE (-1). Because the parameter was declared 'unsigned', the value
becomes UINT_MAX and the index walks off the array (sized to nr_node_ids), faulting during nvme_alloc_ns()
and leaving the namespace without a /dev node. Reproduces on any NVMe controller probed by a CONFIG_NUMA=n
kernel: BUG: unable to handle page fault for address: ffff889101603d38 RIP:
0010:nvme_init_hctx_common+0x5a/0x190 [nvme] Call Trace: nvme_init_hctx+0x10/0x20 [nvme]
nvme_alloc_ns+0x9e/0xa10 [nvme_core] nvme_scan_ns+0x301/0x3b0 [nvme_core] nvme_scan_ns_async+0x23/0x30
[nvme_core] Switch the parameter to int and fall back to node 0 when it is NUMA_NO_NODE; node 0 is always
present. (CVE-2026-74383)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19999.44.21 or later.
