CVE-2022-50485: ext4: add EXT4_IGET_BAD flag to prevent unexpected bad inode
Noroxi assessment
Priority: Monitor (action score 22/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 2142dfa1de61e25b83198af0308ec7689cca25d3, 488a5c2bf7543c3cd3f07a025f2e62be91599430, 63b1e9bccb71fe7d7e3ddc9877dbdc85e5d2d023.
Low priority for now. Upgrade to Linux Linux 2142dfa1de61e25b83198af0308ec7689cca25d3, 488a5c2bf7543c3cd3f07a025f2e62be91599430, 63b1e9bccb71fe7d7e3ddc9877dbdc85e5d2d023 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: ext4: add EXT4_IGET_BAD flag to prevent unexpected bad inode There are many places that will get unhappy (and crash) when ext4_iget() returns a bad inode. However, if iget the boot loader inode, allows a bad inode to be returned, because the inode may not be initialized. This mechanism can be used to bypass some checks and cause panic. To solve this problem, we add a special iget flag EXT4_IGET_BAD. Only with this flag we'd be returning bad inode from ext4_iget(), otherwise we always return the error code if the inode is bad inode.(suggested by Jan Kara)
