The vulnerability of the fcntl_setlk() function in the Linux operating system allows a hacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the fcntlsetlk function in the fs/locks.c module of the Linux operating system is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the protected...

CVE-2024-41020

CVE-2024-41020 is a Linux kernel vulnerability fixed by applying the same fcntl/close race recovery patch to the compat path for 32-bit kernels. The issue concerns a race condition in filelock handling during fcntl/close, resolved by ensuring reliable lock removal across both normal and 32-bit co...

CVE-2024-41012

In the Linux kernel, CVE-2024-41012 pertains to a fcntl/close race in file locking where an LSM could allow the first do_lock_file_wait() to acquire a lock while denying the second removal, and POSIX lock removal could fail due to GFP_KERNEL allocation during range splitting. The issue can lead t...
