K000139682: Speculative race conditions vulnerabilities CVE-2024-2193 and CVE-2024-26602

Security Advisory Description

• CVE-2024-2193
  A Speculative Race Condition (SRC) vulnerability that impacts modern CPU architectures supporting speculative execution (related to Spectre V1) has been disclosed. An unauthenticated attacker can exploit this vulnerability to disclose arbitrary data from the CPU using race conditions to access the speculative executable code paths.
• CVE-2024-26602
  In the Linux kernel, the following vulnerability has been resolved: sched/membarrier: reduce the ability to hammer on sys_membarrier On some systems, sys_membarrier can be very expensive, causing overall slowdowns for everything. So put a lock on the path in order to serialize the accesses to prevent the ability for this to be called at too high of a frequency and saturate the machine.

Impact

An authenticated attacker can exploit this vulnerability to disclose arbitrary data from the CPU using race conditions to access the speculative executable code paths.

For products with Nonein the Versions known to be vulnerable column, there is no impact.

For products with ****** in the various columns, F5 is still researching the issue and will update this article after confirming the required information. F5 Support has no additional information about this issue.
