CVE-2023-53766 [MEDIUM] CWE-476 kernel: FS: JFS: Check for read-only mounted filesystem in txBegin
kernel: FS: JFS: Check for read-only mounted filesystem in txBegin
In the Linux kernel, the following vulnerability has been resolved:
FS: JFS: Check for read-only mounted filesystem in txBegin
This patch adds a check for read-only mounted filesystem
in txBegin before starting a transaction potentially saving
from NULL pointer deref.
JFS filesystem code neglects to verify whether the filesystem is mounted read-only before initiating transactions in txBegin(). When write operations are attempted on a read-only mount, the missing check allows execution to proceed with uninitialized transaction structures, culminating in a NULL pointer dereference and kernel crash.
Statement: JFS usage has declined significantly in modern deployments. Exploitation requires local filesystem access and speci
