CVE-2022-50835 [LOW] CWE-911 kernel: jbd2: add miss release buffer head in fc_do_one_pass()
kernel: jbd2: add miss release buffer head in fc_do_one_pass()
In the Linux kernel, the following vulnerability has been resolved:
jbd2: add miss release buffer head in fc_do_one_pass()
In fc_do_one_pass() miss release buffer head after use which will lead
to reference count leak.
A reference count leak was found in the Linux kernel's JBD2 journaling subsystem. The fc_do_one_pass() function, used during fast commit replay, fails to release a buffer head after use. This results in a reference count leak that can prevent proper buffer memory cleanup over time.
Statement: This issue affects ext4 filesystems using the fast commit feature. The buffer head leak occurs during journal recovery operations, which typically happen at mount time. While repeated mount/unmount cycles could accumulate
