Last modified

CVE-2024-36964 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: fs/9p: only translate RWX permissions for plain 9P2000 Garbage in plain 9P2000's perm bits is allowed through, which causes it to be able to set (among others) the suid bit. This was presumably not the intent since the unix extended bits are handled explicitly and conditionally on .u.. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
