In the Linux kernel, the following vulnerability has been resolved: amdkfd: use calloc instead of kzalloc to avoid integer overflow This uses calloc instead of doing the multiplication which might overflow. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: amdkfd: usa calloc en lugar de kzalloc para evitar el desbordamiento de enteros.

CVSS: -EPSS: 0%CPEs: 9EXPL: 0CVE-2024-26816 – x86, relocs: Ignore relocations in .notes section
https://notcve.org/view.php?id=CVE-2024-26816
In the Linux kernel, the following vulnerability has been resolved: x86, relocs: Ignore relocations in .notes section When building with CONFIG_XEN_PV=y, .text symbols are emitted into the .notes section so that Xen can find the "startup_xen" entry point. This information is used prior to booting the kernel, so relocations are not useful. In fact, performing relocations against the .notes section means that the KASLR base is exposed since /sys/kernel/notes is world-readable. To avoid leaking the KASLR base without breaking unprivileged tools that are expecting to read /sys/kernel/notes, skip performing relocations in the .notes section. The values readable in .notes are then identical to those found in System.map. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: x86, relocs: ignorar reubicaciones en la sección .notes Al compilar con CONFIG_XEN_PV=y, los símbolos .text se emiten en la sección .notes para que Xen pueda encontrar el punto de entrada "startup_xen" . Esta información se utiliza antes de iniciar el kernel, por lo que las reubicaciones no son útiles. • https://git.kernel.org/stable/c/5ead97c84fa7d63a6a7a2f4e9f18f452bd109045 https://git.kernel.org/stable/c/13edb509abc91c72152a11baaf0e7c060a312e03 https://git.kernel.org/stable/c/52018aa146e3cf76569a9b1e6e49a2b7c8d4a088 https://git.kernel.org/stable/c/a4e7ff1a74274e59a2de9bb57236542aa990d20a https://git.kernel.org/stable/c/c7cff9780297d55d97ad068b68b703cfe53ef9af https://git.kernel.org/stable/c/47635b112a64b7b208224962471e7e42f110e723 https://git.kernel.org/stable/c/af2a9f98d884205145fd155304a6955822ccca1c https://git.kernel.org/stable/c/ae7079238f6faf1b94accfccf334e98b4 •
