In the Linux kernel, the following vulnerability has been resolved: net/sched: sch_ets: don't peek at classes beyond 'nbands' The Linux kernel CVE team has assigned CVE-2021-47557 to this issue. Upstream advisory: https://lore.kernel.org/linux-cve-announce/2024052444-CVE-2021-47557-bc88@gregkh/T
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2021-47557 is: CHECK Maybe valid. Check manually. with impact MODERATE (that is an approximation based on flags REMOTE DANGER NULLPTR DISK INIT RACE NETWORK SKB ; 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.
