| Doc Text: |
CVE-2024-35852 addresses a memory leak in the Linux kernel's mlxsw driver, specifically within the Spectrum ACL TCAM module. The issue occurs when rehash work is canceled while pending, leading to allocated hints not being freed properly. This results in a memory leak that can degrade system performance over time. The problem has been resolved by ensuring that any associated hints are freed when the rehash work is canceled. Users should update their Linux kernel to a version that includes this fix to maintain optimal system performance.

Created kernel tracking bugs for this issue: Affects: fedora-all [bug 2281258] The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-35852 is: CHECK Maybe valid. Check manually. with impact MODERATE (that is an approximation based on flags REMOTE LEAK UAF NETWORK ; these flags parsed automatically based on patch data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later.
