A remo...

CVE-2026-46082

CVE-2026-46082 is a Linux kernel KVM vulnerability (SVM) where INVLPGA generates a #UD if EFER.SVME is 0. The issue affects kernel code handling SVM, with local attack potential and high impact on availability, and was addressed by a patch adding a proper #UD injection when EFER.SVME=0. Public re...

CVE-2026-46079 rbd: fix null-ptr-deref when device_add_disk() fails

In the Linux kernel, the following vulnerability has been resolved: rbd: fix null-ptr-deref when deviceadddisk fails dorbdadd publishes the device with deviceadd before calling deviceadddisk. If deviceadddisk fails after deviceadd succeeds, the error path calls rbdfreedisk directly and then later...

CVE-2026-46064

CVE-2026-46064 affects the Linux kernel’s ibmasm_send_i2o_message, where the copy size is derived from user-controlled dot_command_header fields and not validated against allocation size. This can let an attacker perform a heap over-read by memcpy_toio(), reaching up to ~65 KB beyond the allocate...

CVE-2026-46052

The CVE-2026-46052 issue concerns the Linux kernel Ceph filesystem where a negative dentry that is already hashed can be re-added to the dcache, corrupting the d_hash bucket and leading to an RCU stall or system hang. The root cause is that d_add() can rehash and reinstate a dentry that is alread...

CVE-2026-46052 ceph: only d_add() negative dentries when they are unhashed

In the Linux kernel, the following vulnerability has been resolved: ceph: only dadd negative dentries when they are unhashed Ceph can call dadddentry, NULL on a negative dentry that is already present in the primary dcache hash. In the current VFS that is not safe. dadd goes through dadd to...
