The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - drm/amdkfd: Fix watch_id bounds checking in debug address watch v2 The address watch clear code receives     watch_id as an unsigned value (u32), but some helper functions were using a signed int and checked bits by     shifting with watch_id. If a very large watch_id is passed from userspace, it can be converted to a     negative value. This can cause invalid shifts and may access memory outside the watch_points array.
    drm/amdkfd: Fix watch_id bounds checking in debug address watch v2 Fix this by checking that watch_id is     within MAX_WATCH_ADDRESSES before using it. Also use BIT(watch_id) to test and clear bits safely. This     keeps the behavior unchanged for valid watch IDs and avoids undefined behavior for invalid ones. Fixes the     below: drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_debug.c:448 kfd_dbg_trap_clear_dev_address_watch() error:
    buffer overflow 'pdd->watch_points' 4 <= u32max user_rl='0-3,2147483648-u32max' uncapped     drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_debug.c 433 int kfd_dbg_trap_clear_dev_address_watch(struct     kfd_process_device *pdd, 434 uint32_t watch_id) 435 { 436 int r; 437 438 if     (!kfd_dbg_owns_dev_watch_id(pdd, watch_id)) kfd_dbg_owns_dev_watch_id() doesn't check for negative values     so if watch_id is larger than INT_MAX it leads to a buffer overflow.
