https://notcve.org/view.php?id=CVE-2021-47486
In the Linux kernel, the following vulnerability has been resolved: riscv, bpf: Fix potential NULL dereference The bpf_jit_binary_free() function requires a non-NULL argument. When the RISC-V BPF JIT fails to converge in NR_JIT_ITERATIONS steps, jit_data->header will be NULL, which triggers a NULL dereference. Avoid this by checking the argument, prior calling the function. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: riscv, bpf: corrige una posible desreferencia NULL La función bpf_jit_binary_free() requiere un argumento que no sea NULL. Cuando el JIT BPF de RISC-V no logra converger en los pasos NR_JIT_ITERATION, jit_data->header será NULL, lo que desencadena una desreferencia NULL. • https://git.kernel.org/stable/c/ca6cb5447ceca6a87d6b62c9e5d41042c34f7ffa https://git.kernel.org/stable/c/cac6b043cea3e120f4fccec16f7381747cbfdc0d https://git.kernel.org/stable/c/e1b80a5ebe5431caeb20f88c32d4a024777a2d41 https://git.kernel.org/stable/c/27de809a3d83a6199664479ebb19712533d6fd9b • CWE-476: NULL Pointer Dereference •

In the Linux kernel, the following vulnerability has been resolved: IB/qib: Protect from buffer overflow in struct qib_user_sdma_pkt fields Overflowing either addrlimit or bytes_togo can allow userspace to trigger a buffer overflow of kernel memory. Check for overflows in all the places doing math on user controlled buffers. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: IB/qib: Protege contra el desbordamiento del búfer en los campos de struct qib_user_sdma_pkt. El desbordamiento de addrlimit o bytes_togo puede permitir que el espacio de usuario desencadene un desbordamiento del búfer de la memoria del kernel. Compruebe si hay desbordamientos en todos los lugares que realizan cálculos en búferes controlados por el usuario. • https://git.kernel.org/stable/c/f931551bafe1f10ded7f5282e2aa162c267a2e5d https://git.kernel.org/stable/c/bda41654b6e0c125a624ca35d6d20beb8015b5d0 https://git.kernel.org/stable/c/3f57c3f67fd93b4da86aeffea1ca32c484d054ad https://git.kernel.org/stable/c/60833707b968d5ae02a75edb7886dcd4a957cf0d https://git.kernel.org/stable/c/73d2892148aa4397a885b4f4afcfc5b27a325c42 https://git.kernel.org/stable/c/0f8cdfff06829a0b0348b6debc29ff6a61967724 https://git.kernel.org/stable/c/c3e17e58f571f34c51aeb17274ed02c2ed5cf780 https://git.kernel.org/stable/c/0d4395477741608d123dad51def9fe50b •
