CVE-2024-27032
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn the Linux kernel, the following vulnerability has been resolved: f2fs: fix to avoid potential panic during recovery During recovery, if FAULT_BLOCK is on, it is possible that f2fs_reserve_new_block() will return -ENOSPC during recovery, then it may trigger panic. Also, if fault injection rate is 1 and only FAULT_BLOCK fault type is on, it may encounter deadloop in loop of block reservation. Let's change as below to fix these issues: - remove bug_on() to avoid panic. - limit the loop count of block reservation to avoid potential deadloop.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisCrafted input drives a loop whose exit condition is never satisfied, hanging the thread and starving the service of the resource it occupies. A single request can be enough to take a worker down. Remediation is bounding iteration counts and validating the conditions that are supposed to terminate the loop.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped4.205.55.11
For 4.19.x upgrade to 4.20 or later; for 5.4.x upgrade to 5.5 or later; for 5.10.x upgrade to 5.11 or later; for 5.15.x upgrade to 5.16 or later
- Identify the running Linux kernel version using `uname -r`
- Determine which version range your kernel falls into: >= 4.19.307 and < 4.20, >= 5.4.269 and < 5.5, >= 5.10.210 and < 5.11, or >= 5.15.149 and < 5.16
- Upgrade the kernel to the next stable release in your version branch that includes the fix (e.g., for 5.15.x branch, upgrade to 5.16 or later; for 5.10.x branch, upgrade to 5.11 or later)
- Reboot the system to load the patched kernel
- Verify the fix is applied by checking the f2fs module or kernel version
