CVE-2023-42752 – Kernel: integer overflow in igmpv3_newpack leading to exploitable memory access
https://notcve.org/view.php?id=CVE-2023-42752
An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating `skb_shared_info` in the userspace, which is exploitable in systems without SMAP protection since `skb_shared_info` contains references to function pointers. Se encontró una falla de desbordamiento de enteros en el kernel de Linux. Este problema lleva a que el kernel asigne `skb_shared_info` en el espacio de usuario, lo cual es explotable en sistemas sin protección SMAP ya que `skb_shared_info` contiene referencias a punteros de función. • http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://access.redhat.com/security/cve/CVE-2023-42752 https://bugzilla.redhat.com/show_bug.cgi?id=2239828 https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=915d975b2ffa https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=c3b704d4a4a2 • CWE-190: Integer Overflow or Wraparound •
CVE-2023-39189 – Kernel: netfilter: nftables out-of-bounds read in nf_osf_match_one()
https://notcve.org/view.php?id=CVE-2023-39189
A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure. Se encontró una falla en el subsistema Netfilter en el kernel de Linux. La función nfnl_osf_add_callback no validó el campo opt_num controlado por el modo de usuario. • https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-39189 https://bugzilla.redhat.com/show_bug.cgi?id=2226777 https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html • CWE-125: Out-of-bounds Read •
