It is because that skb->len requires at least sizeof(struct qrtr_ctrl_pkt) in qrtr_tx_resume(). And skb->len equals to size in qrtr_endpoint_post(). But size is less than sizeof(struct qrtr_ctrl_pkt) when qrtr_cb->type equals to QRTR_TYPE_RESUME_TX in qrtr_endpoint_post() under the syzbot scenario. This triggers the uninit variable access bug.
Add size check when qrtr_cb->type equals to QRTR_TYPE_RESUME_TX in qrtr_endpoint_post() to fix the bug.

The following simple reproducer can cause the issue described above:
int main(void) { int sock; struct sockaddr_vm addr = { .svm_family = AF_VSOCK, .svm_cid = VMADDR_CID_ANY, .svm_port = 1234, };
sock = socket(AF_VSOCK, SOCK_STREAM, 0); connect(sock, (struct sockaddr *)&addr, sizeof(addr)); return 0; }
This issue occurs because the buf_alloc and fwd_cnt fields of the
struct virtio_vsock_hdr are not initialized when a new skb is allocated
in virtio_transport_init_hdr(). This patch resolves the issue by
initializing these fields during allocation.

Vulnerability from github – Published: 2024-12-28 12:30 – Updated: 2025-11-03 21:32In the Linux kernel, the following vulnerability has been resolved:
powerpc/fadump: Move fadump_cma_init to setup_arch() after initmem_init()
During early init CMA_MIN_ALIGNMENT_BYTES can be PAGE_SIZE, since pageblock_order is still zero and it gets initialized later during initmem_init() e.g. setup_arch() -> initmem_init() -> sparse_init() -> set_pageblock_order()
One such use case where this causes issue is - early_setup() -> early_init_devtree() -> fadump_reserve_mem() -> fadump_cma_init()
This causes CMA memory alignment check to be bypassed in cma_init_reserved_mem(). Then later cma_activate_area() can hit a VM_BUG_ON_PAGE(pfn & ((1 << order) - 1)) if the reserved memory area was not pageblock_order aligned.
Fix it by moving the fadump_cma_init() after initmem_init(), where other such cma reservations also gets called.

Mitigation
Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.
Mitigation
Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.
Mitigation
Avoid race conditions (CWE-362) during initialization routines.
Mitigation
Run or compile the product with settings that generate warnings about uninitialized variables or data.
No CAPEC attack patterns related to this CWE.
