CVE-2022-49645

CVE-2022-49645 affects the Linux kernel (drm/panfrost). The issue occurs when the madvise IOCTL is called twice on a BO: the memory shrinker list is corrupted because the BO is already on the list and is re-added without removing it first, leading to a kernel crash. The connected documents confir...

CVE-2022-49556

The CVE-2022-49556 issue affects the Linux kernel KVM: SVM sev ioctl interfaces. It could cause leakage of uninitialized kernel memory when the length parameter is between SEV_FW_BLOB_MAX_SIZE and the returned data, due to using kmalloc. The fix uses kzalloc for sev ioctl interfaces to allocate c...

CVE-2022-49291 ALSA: pcm: Fix races among concurrent hw_params and hw_free calls

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fix races among concurrent hwparams and hwfree calls Currently we have neither proper check nor protection against the concurrent calls of PCM hwparams and hwfree ioctls, which may result in a UAF. Since the existing P...

CVE-2022-49271

CVE-2022-49271 affects the Linux kernel CIFS/SMB2 code. When smb2_ioctl_query_info() is called with flags=PASSTHRU_FSCTL and output_buffer_length=0, the kernel could copy a bad pointer (buffer) and end up dereferencing NULL, potentially leading to a NULL pointer dereference. The fix also ensures ...
