kernel: mm/huge_memory: update file PMD counter before folio_put()

A flaw was found in the Linux kernel's memory management, specifically within the huge page mechanism. When a huge page is split, the system updates a counter after releasing a reference to the memory. This timing issue can lead to the system attempting to read from memory that has already been...

kernel: zram: fix use-after-free in zram_bvec_write_partial()

A flaw was found in the Linux kernel, specifically within the zram module. This vulnerability is a use-after-free error, where the system attempts to use a piece of memory after it has been freed. This occurs when the zrambvecwritepartial function allows an asynchronous read to write into a page...

kernel: nfsd: release layout stid on setlease failure

A flaw was found in the Linux kernel's Network File System Daemon nfsd. When a setlease operation fails, the system prematurely releases a layout state identifier. An attacker could exploit this by triggering the failure, leading to a use-after-free vulnerability. This could result in a system...

kernel: netfilter: ipset: fix race between dump and ip_set_list resize

A flaw was found in the Linux kernel's netfilter ipset component. A race condition exists between the ipsetlist resize operation and dump operations. This can lead to a use-after-free vulnerability, where memory is accessed after it has been deallocated. A successful exploitation of this flaw cou...

kernel: mm: shrinker: fix shrinker_info teardown race with expansion

A flaw was found in the Linux kernel's memory management mm shrinker subsystem. A race condition exists where the shrinkerinfo array can be prematurely freed while still accessible, leading to a use-after-free or double-free vulnerability. This memory corruption can be exploited by a local attack...

kernel: crypto: qat - fix VF2PF work teardown race in adf_disable_sriov()

A flaw was found in the Linux kernel's crypto QAT QuickAssist Technology module. A race condition exists during the teardown of Virtual Function to Physical Function VF2PF work in the adfdisablesriov function. This allows a concurrently scheduled or already queued worker to attempt to access memo...

kernel: locking/rt: Fix the incorrect RCU protection in rt_spin_unlock()

A flaw was found in the Linux kernel. The rtspinunlock function, and similar real-time RT locking mechanisms, incorrectly release Read-Copy-Update RCU protection before fully unlocking, leading to a Use-After-Free UAF vulnerability. This issue could allow a local attacker to potentially cause a...

CVE-2026-80716

A flaw was found in the Linux kernel. Specifically, in the Advanced Linux Sound Architecture ALSA Pulse-Code Modulation PCM subsystem, a use-after-free vulnerability exists.
