Description

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check for potential null return of kmalloc_array() As the kmalloc_array() may return null, the 'event_waiters[i].wait' would lead to null-pointer dereference. Therefore, it is better to check the return value of kmalloc_array() to avoid this confusion.

Affected configurations

• linux linux kernel (< 4.9.311) • linux linux kernel (>= 4.10 < 4.14.276) • linux linux kernel (>= 4.15 < 4.19.239) • linux linux kernel (>= 4.20 < 5.4.190) • linux linux kernel (>= 5.5 < 5.10.112) • linux linux kernel (>= 5.11 < 5.15.35) • linux linux kernel (>= 5.16 < 5.17.4) • linux linux kernel 5.18
