high Tenable Cloud Security Plugin ID 469146

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: scsi: target: configfs: Bound
snprintf() return in tg_pt_gp_members_show() target_tg_pt_gp_members_show() formats LUN paths with
snprintf() into a 256-byte stack buffer, then will memcpy() cur_len bytes from that buffer. snprintf()
returns the length the output would have had, which can exceed the buffer size when the fabric WWN is long
because iSCSI IQN names can be up to 223 bytes. The check at the memcpy() site only guards the destination
page write, not the source read, so memcpy() will read past the stack buffer and copy adjacent stack
contents to the sysfs reader, which when CONFIG_FORTIFY_SOURCE is enabled, fortify_panic() will be
triggered. Commit 27e06650a5ea ("scsi: target: target_core_configfs: Add length check to avoid buffer
overflow") added the same bound to the target_lu_gp_members_show() but the tg_pt_gp variant was missed so
resolve that here. (CVE-2026-46149)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.224.7 or later.
