In the Linux kernel, the following vulnerability has been resolved: riscv: Check if the code to patch lies in the exit section Otherwise we fall through to vmalloc_to_page() which panics since the address does not lie in the vmalloc region. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: riscv: compruebe si el código a parchear se encuentra en la sección de salida. De lo contrario, caeremos en vmalloc_to_page(), lo que entra en pánico ya que la dirección no se encuentra en la región vmalloc. • https://git.kernel.org/stable/c/043cb41a85de1c0e944da61ad7a264960e22c865 https://git.kernel.org/stable/c/938f70d14618ec72e10d6fcf8a546134136d7c13 https://git.kernel.org/stable/c/890cfe5337e0aaf03ece1429db04d23c88da72e7 https://git.kernel.org/stable/c/8db56df4a954b774bdc68917046a685a9fa2e4bc https://git.kernel.org/stable/c/1d7a03052846f34d624d0ab41a879adf5e85c85f https://git.kernel.org/stable/c/420370f3ae3d3b883813fd3051a38805160b2b9f •
CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2023-52676 – bpf: Guard stack limits against 32bit overflow
https://notcve.org/view.php?id=CVE-2023-52676
In the Linux kernel, the following vulnerability has been resolved: bpf: Guard stack limits against 32bit overflow This patch promotes the arithmetic around checking stack bounds to be done in the 64-bit domain, instead of the current 32bit. The arithmetic implies adding together a 64-bit register with a int offset. The register was checked to be below 1<<29 when it was variable, but not when it was fixed. The offset either comes from an instruction (in which case it is 16 bit), from another register (in which case the caller checked it to be below 1<<29 [1]), or from the size of an argument to a kfunc (in which case it can be a u32 [2]). Between the register being inconsistently checked to be below 1<<29, and the offset being up to an u32, it appears that we were open to overflowing the `int`s which were currently used for arithmetic.
