kernel: KVM: NULL pointer dereference in kvm_irq_delivery_to_apic_fast()

A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a...

kernel: concurrency use-after-free between drm_setmaster_ioctl and drm_mode_getresources

A use-after-free vulnerability was found in drmleaseheld in drivers/gpu/drm/drmlease.c in the Linux kernel due to a race problem. This flaw allows a local user privilege attacker to cause a denial of service DoS or a kernel information leak...

kernel: ALSA: pcm: Fix potential AB/BA lock with buffer_mutex and mmap_lock

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fix potential AB/BA lock with buffermutex and mmaplock syzbot caught a potential deadlock between the PCM runtime-buffermutex and the mm-mmaplock. It was brought by the recent fix to cover the racy read/write and other...

kernel: smb2_ioctl_query_info NULL pointer dereference

A denial of service DOS issue was found in the Linux kernel’s smb2ioctlqueryinfo function in the fs/cifs/smb2ops.c Common Internet File System CIFS due to an incorrect return from the memdupuser function. This flaw allows a local, privileged CAPSYSADMIN attacker to crash the system...

kernel: dm ioctl: prevent potential spectre v1 gadget

A vulnerability was found in the Linux kernel's dm-ioctl interface in the lookupioctl function, which accepts a user-provided cmd value that is used to index the ioctls array directly. This issue could lead to an out-of-bounds access if the CPU speculatively executes the array access before cmd i...

kernel: KVM: NULL pointer dereference in kvm_dirty_ring_push in virt/kvm/dirty_ring.c

A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service...
