https://notcve.org/view.php?id=CVE-2022-49897
01 May 2025 — In the Linux kernel, the following vulnerability has been resolved: fscrypt: fix keyring memory leak on mount failure Commit d7e7b9af104c ("fscrypt: stop using keyrings subsystem for fscrypt_master_key") moved the keyring destruction from __put_super() to generic_shutdown_super() so that the filesystem's block device(s) are still available. Unfortunately, this causes a memory leak in the case where a mount is attempted with the test_dummy_encryption mount option, but the mount fails after the option has alr... • https://git.kernel.org/stable/c/ccd30a476f8e864732de220bd50e6f372f5ebcab •

CVE-2022-49892 – ftrace: Fix use-after-free for dynamic ftrace_ops

01 May 2025 — In the Linux kernel, the following vulnerability has been resolved: ftrace: Fix use-after-free for dynamic ftrace_ops KASAN reported a use-after-free with ftrace ops [1]. It was found from vmcore that perf had registered two ops with the same content successively, both dynamic. After unregistering the second ops, a use-after-free occurred. In ftrace_shutdown(), when the second ops is unregistered, the FTRACE_UPDATE_CALLS command is not set because there is another enabled ops with the same content. Also, bo... • https://git.kernel.org/stable/c/edb096e00724f02db5f6ec7900f3bbd465c6c76f •
