A use-after-free flaw was discovered in the ext4remount function in the fs/ext4/super.c file within ext4 in the Linux kernel. This flaw allows a local user to cause an information leak issue when freeing the old quota file names before a potential failure, resulting in a use-after-free condition...
CVE-2026-63804
In the Linux kernel, the following vulnerability has been resolved: gfs2: fix use-after-free in gfs2qddealloc gfs2qddealloc, called as an RCU callback from gfs2qddispose, accesses the superblock object sdp through qd-qdsbd after freeing qd. It does so to decrement sdquotacount and wake up...
CVE-2026-63804
The CVE-2026-63804 issue is a gfs2 use-after-free in gfs2_qd_dealloc triggered by an RCU callback accessing sdp after qd is freed. The root cause is that gfs2_put_super() may free the superblock via free_sbd() before pending RCU callbacks (including gfs2_qd_dealloc) complete. The public details i...
