Doc Text:	CVE-2023-52672 is a vulnerability in the Linux kernel's pipe subsystem caused by a regression in how pipes are resized. When a pipe is full and resized, incorrect handling of wakeups for writers can lead to deadlocks or system lockups. This issue has been resolved by ensuring that the pipe's usage limits are updated before wakeup calls are triggered, avoiding race conditions. Updating to a patched kernel version will mitigate this vulnerability and ensure system stability.	Story Points:	---

Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2281341]

Comment 3 Alex 2024-06-09 15:36:32 UTC

The result of automatic check (that is developed by Alexander Larkin) for this CVE-2023-52672 is: CHECK	Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags DISK  ; these flags parsed automatically based on patche 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.
