Oracle Linux 8 : kernel (ELSA-2026-45115)
The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-45115 advisory. - KVM: x86/mmu: Ensure hugepage is in by slot before checking max mapping level Aidan Wallace RHEL-213341 CVE-2026-63807 - KVM: x86: Don't recheck L1...
kernel: dm log: fix out-of-bounds write due to region_count overflow
A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...

SUSE CVE-2026-53059
In the Linux kernel, the following vulnerability has been resolved: dm log: fix out-of-bounds write due to regioncount overflow The local variable regioncount in createlogcontext is declared as unsigned int 32-bit, but dmsectordivup returns sectort 64-bit. When a device-mapper target has a...
SUSE CVE-2026-53062
In the Linux kernel, the following vulnerability has been resolved: dm cache policy smq: fix missing locks in invalidating cache blocks In passthrough mode, the policy invalidatemapping operation is called simultaneously from multiple workers, thus it should be protected by a lock. Otherwise, we...

CVE-2026-53064
A flaw was found in the Linux kernel's device-mapper dm-cache component. When dm-cache operates in passthrough mode, a race condition can occur during concurrent write operations to the same cached block. This can lead to a null-pointer dereference in the invalidatecomplete function, potentially...
CVE-2026-53063
A flaw was found in the Linux kernel's device-mapper dm cache component. Incomplete logic within the invalidateremove function, which handles write operations after cache invalidation, can lead to a system hang. This occurs because the function sets up remapping for write operations but fails to...
CVE-2026-53060
A flaw was found in the Linux kernel's device-mapper dm cache metadata. This memory leak vulnerability occurs when the dmcachemetadataabort function fails to acquire the root lock because the block manager is read-only, leading to the improper release of a temporary block manager. A local attacke...
SUSE CVE-2026-53064
In the Linux kernel, the following vulnerability has been resolved: dm cache: fix null-deref with concurrent writes in passthrough mode In passthrough mode, when dm-cache starts to invalidate a cache entry and bio prison cell lock fails due to concurrent write to the same cached block, mg-cell...
