CVE-2024-56697

CVE-2024-56697 affects the Linux kernel DRM/AMDGPU path. The issue was a memory allocation problem in amdgpu_discovery_get_nps_info() (mem_ranges) that could dereference a NULL pointer. The fix adds a failure check, switches to kvcalloc() to guard against integer overflow, and assigns output para...

CVE-2024-56695 drm/amdkfd: Use dynamic allocation for CU occupancy array in 'kfd_get_cu_occupancy()'

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Use dynamic allocation for CU occupancy array in 'kfdgetcuoccupancy' The kfdgetcuoccupancy function previously declared a large cuoccupancy array as a local variable, which could lead to stack overflows due to excessi...

CVE-2024-56695

CVE-2024-56695 affects the Linux kernel’s AMDGPU/KFD subsystem. The vulnerability arose from a large local cu_occupancy array in kfd_get_cu_occupancy(), risking stack overflow when AMDGPU_MAX_QUEUES is large. The fix replaces the static stack allocation with dynamic memory via kcalloc and ensures...

In the Linux kernel, the following vulnerability has been resolved: brd: defer automatic disk creation until module initialization succeeds My colleague Wupeng found the following problems during fault injection: BUG: unable to handle page fault for address: fffffbfff809d073 PGD 6e648067 P4D...

CVE-2024-56693

The connected material describes CVE-2024-56693, a Linux kernel issue in the brd (RAM block device) and brd_init path that can lead to a use-after-free (UAF) when modprobe brd triggers error paths. Root cause: loop_init() in the kernel’s loop device code adds disks only after successful blkdev re...

CVE-2024-56681

CVE-2024-56681 : In the Linux kernel, the bcm crypto driver’s ahash_hmac_init path can return success even if the underlying ahash_init call fails (e.g., -ENOMEM). This describes a failure to propagate initialization errors from ahash_init, potentially leaving the HMAC/AHASH state inconsistently ...
