Vulnerability description
DayBreach CVE AI Research
CVE-2022-2327 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
io_uring use work_flags to determine which identity need to grab from the calling process to make sure it is consistent with the calling process when executing IORING_OP. Some operations are missing some types, which can lead to incorrect reference counts which can then lead to a double free. We recommend upgrading the kernel past commit df3f3bb5059d20ef094d6b2f0256c4bf4127a859
