Linux: Out-of-bounds Read
CVE-2024-50158 is a high-severity out-of-bounds read vulnerability in Linux, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 05c5fcc1869a08e36a29691699b6534e5a00a82b, c11b9b03ea5252898f91f3388c248f0dc47bda52, a9e6e7443922ac0a48243c35d03834c96926bff1 as the first without the flaw, so updating Linux to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.23% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Linux to 05c5fcc1869a08e36a29691699b6534e5a00a82b or c11b9b03ea5252898f91f3388c248f0dc47bda52 or a9e6e7443922ac0a48243c35d03834c96926bff1, whichever matches your release line, or a later version.
- Update Linux Kernel to 6.6.59 or 6.11.6, whichever matches your release line, or a later version.

Official description
In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Fix out of bound check Driver exports pacing stats only on GenP5 and P7 adapters. But while parsing the pacing stats, driver has a check for "rdev->dbr_pacing". This caused a trace when KASAN is enabled. BUG: KASAN: slab-out-of-bounds in bnxt_re_get_hw_stats+0x2b6a/0x2e00 [bnxt_re] Write of size 8 at addr ffff8885942a6340 by task modprobe/4809

The underlying weakness: Out-of-bounds Read
The product reads data past the end, or before the beginning, of the intended buffer.
How developers prevent this class of flaw
- Use a language that provides appropriate memory abstractions.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
