High	7.0	EPSS 0.1%	CVE-2025-40242Linux kernel · gfs2: Fix unlikely race in gdlm_put_lock In gdlm_put_lock(), there is a small High7.0EPSS 0.1%2025-12-04GCVE DatabaseCVE-2025-40242 A high-severity race condition vulnerability in the Linux kernel's gfs2 filesystem was resolved. The issue occurs in the gdlm_put_lock() function where a small timing window allows the DFL_UNMOUNT flag to be set while the lockspace has not yet been released. During this window, calls to gdlm_ast() and gdlm_bast() may dereference freed glock objects, leading to potential kernel memory corruption. The fix ensures that glock objects are only freed after the lockspace has been fully released. EPSS 0.1%Vulnerability #ghsa-4g8j-hwjq-h8fr	GCVE Database	2025-12-04
