In the Linux kernel, the following vulnerability has been resolved: drm: bridge: cdns-mhdp8546: Fix possible null pointer dereference In cdns_mhdp_atomic_enable(), the return value of drm_mode_duplicate() is assigned to mhdp_state->current_mode, and there is a dereference of it in drm_mode_set_name(), which will lead to a NULL pointer dereference on failure of drm_mode_duplicate(). Fix this bug add a check of mhdp_state->current_mode. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm: bridge: cdns-mhdp8546: corrige posible desreferencia del puntero nulo En cdns_mhdp_atomic_enable(), el valor de retorno de drm_mode_duplicate() se asigna a mhdp_state->current_mode, y hay una desreferencia de él en drm_mode_set_name(), lo que conducirá a una desreferencia del puntero NULL en caso de falla de drm_mode_duplicate(). Solucione este error y agregue una verificación de mhdp_state->current_mode. • https://git.kernel.org/stable/c/fb43aa0acdfd600c75b8c877bdf9f6e9893ffc9b https://git.kernel.org/stable/c/85d1a27402f81f2e04b0e67d20f749c2a14edbb3 https://git.kernel.org/stable/c/89788cd9824c28ffcdea40232c458233353d1896 https://git.kernel.org/stable/c/ca53b7efd4ba6ae92fd2b3085cb099c745e96965 https://git.kernel.org/stable/c/dcf53e6103b26e7458be71491d0641f49fbd5840 https://git.kernel.org/stable/c/32fb2ef124c3301656ac6c789a2ef35ef69a66da https://git.kernel.org/stable/c/47889711da20be9b43e1e136e5cb68df37cbcc79 https://git.kernel.org/stable/c/935a92a1c400285545198ca2800a4c6c5 • CWE-476: NULL Pointer Dereference •

In the Linux kernel, the following vulnerability has been resolved: media: atomisp: ssh_css: Fix a null-pointer dereference in load_video_binaries The allocation failure of mycs->yuv_scaler_binary in load_video_binaries() is followed with a dereference of mycs->yuv_scaler_binary after the following call chain: sh_css_pipe_load_binaries() |-> load_video_binaries(mycs->yuv_scaler_binary == NULL) | |-> sh_css_pipe_unload_binaries() |-> unload_video_binaries() In unload_video_binaries(), it calls to ia_css_binary_unload with argument &pipe->pipe_settings.video.yuv_scaler_binary[i], which refers to the same memory slot as mycs->yuv_scaler_binary. Thus, a null-pointer dereference is triggered. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: media: atomisp: ssh_css: corrige una desreferencia de puntero nulo en load_video_binaries La falla de asignación de mycs->yuv_scaler_binary en load_video_binaries() va seguida de una desreferencia de mycs->yuv_scaler_binary después de siguiente cadena de llamadas: sh_css_pipe_load_binaries() |-> load_video_binaries(mycs->yuv_scaler_binary == NULL) | |-> sh_css_pipe_unload_binaries() |-> unload_video_binaries() En unload_video_binaries(), llama a ia_css_binary_unload con el argumento &pipe->pipe_settings.video.yuv_scaler_binary[i], que se refiere a la misma ranura de memoria que mycs->yuv_scaler_binary.

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix UAF for cq async event The refcount of CQ is not protected by locks. When CQ asynchronous events and CQ destruction are concurrent, CQ may have been released, which will cause UAF. Use the xa_lock() to protect the CQ refcount. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: RDMA/hns: corrige UAF para el evento cq async El recuento de CQ no está protegido por bloqueos. Cuando los eventos asincrónicos de CQ y la destrucción de CQ son simultáneos, es posible que se haya liberado CQ, lo que provocará UAF.

https://notcve.org/view.php?id=CVE-2024-38544
In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix seg fault in rxe_comp_queue_pkt In rxe_comp_queue_pkt() an incoming response packet skb is enqueued to the resp_pkts queue and then a decision is made whether to run the completer task inline or schedule it. Finally the skb is dereferenced to bump a 'hw' performance counter. This is wrong because if the completer task is already running in a separate thread it may have already processed the skb and freed it which can cause a seg fault. This has been observed infrequently in testing at high scale. This patch fixes this by changing the order of enqueuing the packet until after the counter is accessed. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: RDMA/rxe: corrige la falla de segmentación en rxe_comp_queue_pkt En rxe_comp_queue_pkt(), un paquete de respuesta entrante skb se pone en cola en la cola resp_pkts y luego se toma una decisión si se ejecuta la tarea de finalización en línea o programarla. • https://git.kernel.org/stable/c/0b1e5b99a48b5b810e3e38f1d6e0d39306b99ec0 https://git.kernel.org/stable/c/de5a059e36657442b5637cc16df5163e435b9cb4 https://git.kernel.org/stable/c/e0e14dd35d4242340c7346aac60c7ff8fbf87ffc https://git.kernel.org/stable/c/faa8d0ecf6c9c7c2ace3ca3e552180ada6f75e19 https://git.kernel.org/stable/c/21b4c6d4d89030fd4657a8e7c8110fd941049794 https://git.kernel.org/stable/c/bbad88f111a1829f366c189aa48e7e58e57553fc https://git.kernel.org/stable/c/30df4bef8b8e183333e9b6e9d4509d552c7da6eb https://git.kernel.org/stable/c/2b23b6097303ed0ba5f4bc036a1c07b60 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
