Doc Text:	A flaw was found in the Linux kernel's Bluetooth subsystem. When closing a Synchronous Connection-Oriented (SCO) socket, a race condition between socket cleanup and a delayed timeout worker can cause the kernel to reference memory that has already been released. A local user could exploit this use-after-free vulnerability to crash the system, resulting in a Denial of Service (DoS), or potentially execute arbitrary code.	Story Points:	---

Comment 5 Alex 2024-06-09 16:44:24 UTC

The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-27398 is: CHECK	Maybe valid. Check manually. with impact LOW (that is an approximation based on flags REMOTE KASAN UAF NETWORK IMPROVEONLY  ; 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.
