Description Mauro Matteo Cascella 2024-05-22 16:33:20 UTC 
In the Linux kernel, the following vulnerability has been resolved:

sched/psi: Fix use-after-free in ep_remove_wait_queue()

The Linux kernel CVE team has assigned CVE-2023-52707 to this issue.

Upstream advisory:
https://lore.kernel.org/linux-cve-announce/2024052158-CVE-2023-52707-e048@gregkh/T
Comment 5 Alex 2024-06-09 17:19:13 UTC 
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2023-52707 is: CHECK	Maybe valid. Check manually. with impact LOW (that is an approximation based on flags KASAN UAF DMAorINTERRUPT HARDWARE  ; 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.

Changed from Low to Moderate manually (based on that potentially UAF and attack complexity high).
