# CVE-2024-58094

## Summary

- **CVE ID:** CVE-2024-58094
- **Severity:** HIGH
- **CVSS Score:** 7.8 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
- **CWE:** N/A
- **Published:** Apr 16, 2025

## Description

In the Linux kernel, the following vulnerability has been resolved:

jfs: add check read-only before truncation in jfs_truncate_nolock()

Added a check for "read-only" mode in the `jfs_truncate_nolock`
function to avoid errors related to writing to a read-only
filesystem.

Call stack:

block_write_begin() {
  jfs_write_failed() {
    jfs_truncate() {
      jfs_truncate_nolock() {
        txEnd() {
          ...
          log = JFS_SBI(tblk->sb)->log;
          // (log == NULL)

If the `isReadOnly(ip)` condition is triggered in
`jfs_truncate_nolock`, the function execution will stop, and no
further data modification will occur. Instead, the `xtTruncate`
function will be called with the "COMMIT_WMAP" flag, preventing
modifications in "read-only" mode.
