kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected GFN
A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine x86 shadow paging mechanism. This use-after-free vulnerability arises from incorrect handling of Guest Frame Numbers GFNs when guest page tables are modified. A local attacker with control over a guest virtual machine could...

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Fix shadow paging use-after-free due to unexpected role Commit 0cb2af2ea66ad "KVM: x86: Fix shadow paging use-after-free due to unexpected GFN" fixed a shadow paging mismatch between stored and computed GFNs; the bug...
CVE-2026-53342
A flaw was found in the Linux kernel, specifically within the ARM64 architecture's memory management. This vulnerability occurs because the system fails to properly deallocate page tables that have been hot-removed, leading to memory leaks. This can result in incorrect memory usage statistics and...

CVE-2026-53020
A flaw was found in the Linux kernel. A race condition can occur during Translation Lookaside Buffer TLB synchronization when the page table is traversed and modified without properly holding the necessary page table lock. This vulnerability may allow for unpredictable system behavior or...
CVE-2026-53109
A flaw was found in the Linux kernel's powerpc page table fragment handling. During process exit, a race condition can occur where a page table fragment's active flag is not properly cleared. This can lead to a "bad page state" error, potentially causing system instability or a Denial of Service...
CVE-2026-53277
A flaw was found in the Kernel-based Virtual Machine KVM component of the Linux kernel on arm64 architectures. This vulnerability occurs because certain page table walk operations, used in fault injection and Address Translation AT emulation, do not properly acquire a Sleepable Read-Copy Update...
