In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: invoke pm_genpd_remove() before freeing genpd Call pm_genpd_remove() to unregister from global list prior to releasing acp_genpd memory, and clear the pointer after fre...

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: reject mapping a reserved doorbell to a new queue When creating an user-queue, the user space provides a doorbell BO handle and an offset within the bo to obtain a door...

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix aperture mapping leak amdgpu_pci_remove() calls drm_dev_unplug() before invoking the driver fini routines. This causes drm_dev_enter() in amdgpu_ttm_fini() to alway...

In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate num_subauth when copying ACE in set_ntacl_dacl set_ntacl_dacl() copies each ACE from the attacker-controlled stored security descriptor verbatim into the response D...

In the Linux kernel, the following vulnerability has been resolved: ksmbd: bound DACL dedup walk to copied ACEs set_ntacl_dacl() can stop copying ACEs before consuming the full input DACL when size accounting overflows. When that happens, num_aces...

In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate ACE size against SID sub-authorities set_ntacl_dacl() validates sid.num_subauth before copying an ACE, but does not verify that the declared ACE size contains all s...

In the Linux kernel, the following vulnerability has been resolved: audit: fix recursive locking deadlock in audit_dupe_exe() A deadlock occurs in the audit subsystem when duplicating executable-related rules. When a file is moved (e.g., via do_re...
