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.
Affected configurations
• linux linux kernel (>= 2.6.13 < 6.14.2)
• linux linux kernel 2.6.12
