In the Linux kernel, the following vulnerability has been resolved: xprtrdma: fix pointer derefs in error cases of rpcrdma_ep_create If there are failures then we must not leave the non-NULL pointers with the error value, otherwise `rpcrdma_ep_destroy` gets confused and tries free them, resulting in an Oops. • https://git.kernel.org/stable/c/1e7433fb95ccc01629a5edaa4ced0cd8c98d0ae0 https://git.kernel.org/stable/c/9921c866dc369577c3ebb9adf2383b01b58c18de https://git.kernel.org/stable/c/2526d4d8b209dc5ac1fbeb468149774888b2a141 https://git.kernel.org/stable/c/a9c10b5b3b67b3750a10c8b089b2e05f5e176e33 https://access.redhat.com/security/cve/CVE-2022-48773 https://bugzilla.redhat.com/show_bug.cgi?id=2298109 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2024-41008
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: change vm->task_info handling This patch changes the handling and lifecycle of vm->task_info object. The major changes are: - vm->task_info is a dynamically allocated ptr now, and its uasge is reference counted. - introducing two new helper funcs for task_info lifecycle management - amdgpu_vm_get_task_info: reference counts up task_info before returning this info - amdgpu_vm_put_task_info: reference counts down task_info - last put to task_info() frees task_info from the vm. This patch also does logistical changes required for existing usage of vm->task_info. V2: Do not block all the prints when task_info not found (Felix) V3: Fixed review comments from Felix - Fix wrong indentation - No debug message for -ENOMEM - Add NULL check for task_info - Do not duplicate the debug messages (ti vs no ti) - Get first reference of task_info in vm_init(), put last in vm_fini() V4: Fixed review comments from Felix - fix double reference increment in create_task_info - change amdgpu_vm_get_task_info_pasid - additional changes in amdgpu_gem.c while porting • https://git.kernel.org/stable/c/b8f67b9ddf4f8fe6dd536590712b5912ad78f99c https://access.redhat.com/security/cve/CVE-2024-41008 https://bugzilla.redhat.com/show_bug.cgi?id=2298079 • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') •
