In the Linux kernel, the following vulnerability has been resolved: fsl/fman: Fix refcount handling of fman-related devices In mac_probe() there are multiple calls to of_find_device_by_node(), fman_bind() and fman_port_bind() which takes references to of_dev->dev. Not all references taken by these calls are released later on error path in mac_probe() and in mac_remove() which lead to reference leaks. Add references release. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: fsl/fman: se ha corregido el manejo de refcount de dispositivos relacionados con fman En mac_probe() hay múltiples llamadas a of_find_device_by_node(), fman_bind() y fman_port_bind() que toman referencias a of_dev->dev. No todas las referencias tomadas por estas llamadas se liberan más tarde en la ruta de error en mac_probe() y en mac_remove(), lo que provoca fugas de referencias. Agregar referencias release. • https://git.kernel.org/stable/c/3933961682a30ae7d405cda344c040a129fea422 https://git.kernel.org/stable/c/5ed4334fc9512f934fe2ae9c4cf7f8142e451b8b https://git.kernel.org/stable/c/3c2a3619d565fe16bf59b0a047bab103a2ee4490 https://git.kernel.org/stable/c/1dec67e0d9fbb087c2ab17bf1bd17208231c3bb1 •

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix overloading of MEM_UNINIT's meaning Lonial reported an issue in the BPF verifier where check_mem_size_reg() has the following code: if (!tnum_is_const(reg->var_off)) /* For unprivileged variable accesses, disable raw * mode so that the program is required to * initialize all the memory that the helper could * just partially fill up. */ meta = NULL; This means that writes are not checked when the register containing the size of the passed buffer has not a fixed size. Through this bug, a BPF program can write to a map which is marked as read-only, for example, .rodata global maps. The problem is that MEM_UNINIT's initial meaning that "the passed buffer to the BPF helper does not need to be initialized" which was added back in commit 435faee1aae9 ("bpf, verifier: add ARG_PTR_TO_RAW_STACK type") got overloaded over time with "the passed buffer is being written to". The problem however is that checks such as the above which were added later via 06c1c049721a ("bpf: allow helpers access to variable memory") set meta to NULL in order force the user to always initialize the passed buffer to the helper. Due to the current double meaning of MEM_UNINIT, this bypasses verifier write checks to the memory (not boundary checks though) and only assumes the latter memory is read instead. Fix this by reverting MEM_UNINIT back to its original meaning, and having MEM_WRITE as an annotation to BPF helpers in order to then trigger the BPF verifier checks for writing to memory. Some notes: check_arg_pair_ok() ensures that for ARG_CONST_SIZE{,_OR_ZERO} we can access fn->arg_type[arg - 1] since it must contain a preceding ARG_PTR_TO_MEM. For check_mem_reg() the meta argument can be removed altogether since we do check both BPF_READ and BPF_WRITE. • https://git.kernel.org/stable/c/7b3552d3f9f6897851fc453b5131a967167e43c2 https://git.kernel.org/stable/c/6099a6c8a749a5c8d5f8b4c4342022a92072a02b https://git.kernel.org/stable/c/bfe25df63048edd4ceaf78a2fc755d5e2befc978 https://git.kernel.org/stable/c/717c39718dbc4f7ebcbb7b625fb11851cd9007fe https://git.kernel.org/stable/c/5d0bba8232bf22ce13747cbfc8f696318ff01a50 https://git.kernel.org/stable/c/70674d11d14eeecad90be4b409a22b902112ba32 https://git.kernel.org/stable/c/a08d942ecbf46e23a192093f6983cb1d779f4fa8 https://git.kernel.org/stable/c/48068ccaea957469f1adf78dfd2c1c9a7 •
