CVE-2025-21893
CVE-2025-21893 concerns a use-after-free in the Linux kernel key handling. The issue arises when the key’s usage reaches 0 and the garbage collector may touch the key after it could have been freed. The fix changes the reclamation logic from inspecting the key’s refcount in the garbage collector ...
CVE-2025-21893
In the Linux kernel, the following vulnerability has been resolved: keys: Fix UAF in keyput Once a key's reference count has been reduced to 0, the garbage collector thread may destroy it at any time and so keyput is not allowed to touch the key after that point. The most keyput is normally allow...
The vulnerability of the extent_write_locked_range() function in the file system of the Linux operating system’s kernel allows a hacker to cause a service failure.
The vulnerability of the extentwritelockedrange function in the file system of the Linux operating system’s kernel relates to improper memory release before deleting the last reference. Exploiting this vulnerability could allow an attacker to cause a service failure...
