29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: xfs: don't walk off the end of a directory data block This adds sanity checks for xfs_dir2_data_unused and xfs_dir2_data_entry to make sure don't stray beyond valid memory region. Before patching, the loop simply checks that the start offset of the dup and dep is within the range. So in a crafted image, if last entry is xfs_dir2_data_unused, we can change dup->length to dup->length-1 and leave 1 byte of space. In the next traversal, this sp... • https://git.kernel.org/stable/c/ca96d83c93071f95cf962ce92406621a472df31b • CWE-125: Out-of-bounds Read •

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: tun: add missing verification for short frame The cited commit missed to check against the validity of the frame length in the tun_xdp_one() path, which could cause a corrupted skb to be sent downstack. Even before the skb is transmitted, the tun_xdp_one-->eth_type_trans() may access the Ethernet header although it can be less than ETH_HLEN. Once transmitted, this could either cause out-of-bound access beyond the actual length, or confuse t... • https://git.kernel.org/stable/c/043d222f93ab8c76b56a3b315cd8692e35affb6c • CWE-20: Improper Input Validation •

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: tap: add missing verification for short frame The cited commit missed to check against the validity of the frame length in the tap_get_user_xdp() path, which could cause a corrupted skb to be sent downstack. Even before the skb is transmitted, the tap_get_user_xdp()-->skb_set_network_header() may assume the size is more than ETH_HLEN.

23 Sep 2022 — There exists an arbitrary memory read within the Linux Kernel BPF - Constants provided to fill pointers in structs passed in to bpf_sys_bpf are not verified and can point anywhere, including memory not owned by BPF. An attacker with CAP_BPF can arbitrarily read memory from anywhere on the system. We recommend upgrading past commit 86f44fcec22c Se presenta una lectura de memoria arbitraria dentro del BPF del Kernel de Linux - Las constantes proporcionadas para rellenar los punteros en los structs pasados a b... • https://git.kernel.org/bpf/bpf/c/86f44fcec22c • CWE-125: Out-of-bounds Read •

28 Feb 2014 — The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer. La función cifs_iovec_write en fs/cifs/file.c en el kernel de Linux hasta 3.13.5 no maneja debidamente opera... • http://article.gmane.org/gmane.linux.kernel.cifs/9401 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

21 Dec 2001 — Buffer overflow in glob function of glibc allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a glob pattern that ends in a brace "{" character. Desbordamiento de buffer en la función glob de glibc para Red Hat Linux 6.2 a 7.2, y otros sistemas operativos, permite a atacantes causar una denegación de servicio (caída) y posiblemente ejecutar código arbitrarios mediante un patrón de glob que acaba en una llave "{" • http://distro.conectiva.com.br/atualizacoes/?id=a&anuncio=000447 •
