CVE-2026-99174
The Linux kernel contains a vulnerability in the ext4 filesystem where ext4_put_super() destroys percpu counters, clears sb->s_fs_info, and frees the sbi without waiting for a required grace period. This occurs when a pathwalk is held up in ext4_get_link() while the last reference to the mount...

CVE-2024-39276
A reference count leak exists in the Linux kernel 's ext4 filesystem component within the ext4_xattr_block_cache_find() function. The vulnerability occurs when ext4_sb_bread() returns -ENOMEM; in this scenario, the e_refcnt of the cache entry, which was incremented during __entry_find(), is not p...

kernel: mounting a crafted ext4 filesystem image, performing some operations, and unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c
A flaw was found in the Linux kernel's ext4unlink function. An attacker could corrupt memory or escalate privileges when deleting a file from a recently unmounted specially crafted ext4 filesystem, including local, USB, and iSCSI...
