high Tenable Cloud Security Plugin ID 451242

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: RDMA/umad: Reject negative data_len in
 ib_umad_write ib_umad_write computes data_len from user-controlled count and the MAD header sizes. With a
 mismatched user MAD header size and RMPP header length, data_len can become negative and reach
 ib_create_send_mad(). This can make the padding calculation exceed the segment size and trigger an out-of-
 bounds memset in alloc_send_rmpp_list(). Add an explicit check to reject negative data_len before creating
 the send buffer. KASAN splat: [ 211.363464] BUG: KASAN: slab-out-of-bounds in
 ib_create_send_mad+0xa01/0x11b0 [ 211.364077] Write of size 220 at addr ffff88800c3fa1f8 by task
 spray_thread/102 [ 211.365867] ib_create_send_mad+0xa01/0x11b0 [ 211.365887] ib_umad_write+0x853/0x1c80
 (CVE-2026-23243)
