https://notcve.org/view.php?id=CVE-2024-26668
In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_limit: reject configurations that cause integer overflow Reject bogus configs where internal token counter wraps around. This only occurs with very very large requests, such as 17gbyte/s. Its better to reject this rather than having incorrect ratelimit. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: nft_limit: rechazar configuraciones que causan desbordamiento de enteros Rechazar configuraciones falsas donde el contador de token interno se ajusta. Esto sólo ocurre con solicitudes muy grandes, como 17 gbytes/s. Es mejor rechazar esto en lugar de tener un límite de tasa incorrecto. • https://git.kernel.org/stable/c/d2168e849ebf617b2b7feae44c0c0baf739cb610 https://git.kernel.org/stable/c/79d4efd75e7dbecd855a3b8a63e65f7265f466e1 https://git.kernel.org/stable/c/bc6e242bb74e2ae616bfd2b250682b738e781c9b https://git.kernel.org/stable/c/9882495d02ecc490604f747437a40626dc9160d0 https://git.kernel.org/stable/c/00c2c29aa36d1d1827c51a3720e9f893a22c7c6a https://git.kernel.org/stable/c/c9d9eb9c53d37cdebbad56b91e40baf42d5a97aa https://access.redhat.com/security/cve/CVE-2024-26668 https://bugzilla.redhat.com/show_bug.cgi?id=2272797 • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2024-26667
In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: check for valid hw_pp in dpu_encoder_helper_phys_cleanup The commit 8b45a26f2ba9 ("drm/msm/dpu: reserve cdm blocks for writeback in case of YUV output") introduced a smatch warning about another conditional block in dpu_encoder_helper_phys_cleanup() which had assumed hw_pp will always be valid which may not necessarily be true. Lets fix the other conditional block by making sure hw_pp is valid before dereferencing it. Patchwork: https://patchwork.freedesktop.org/patch/574878/ En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/msm/dpu: check for valid hw_pp en dpu_encoder_helper_phys_cleanup. El commit 8b45a26f2ba9 ("drm/msm/dpu: reserve bloques cdm para reescritura en caso de salida YUV") introdujo una coincidencia advertencia sobre otro bloque condicional en dpu_encoder_helper_phys_cleanup() que había asumido que hw_pp siempre será válido, lo que puede no ser necesariamente cierto. Arreglemos el otro bloque condicional asegurándonos de que hw_pp sea válido antes de eliminar la referencia a él.

In the Linux kernel, the following vulnerability has been resolved: tunnels: fix out of bounds access when building IPv6 PMTU error If the ICMPv6 error is built from a non-linear skb we get the following splat, BUG: KASAN: slab-out-of-bounds in do_csum+0x220/0x240 Read of size 4 at addr ffff88811d402c80 by task netperf/820 CPU: 0 PID: 820 Comm: netperf Not tainted 6.8.0-rc1+ #543 ... kasan_report+0xd8/0x110 do_csum+0x220/0x240 csum_partial+0xc/0x20 skb_tunnel_check_pmtu+0xeb9/0x3280 vxlan_xmit_one+0x14c2/0x4080 vxlan_xmit+0xf61/0x5c00 dev_hard_start_xmit+0xfb/0x510 __dev_queue_xmit+0x7cd/0x32a0 br_dev_queue_push_xmit+0x39d/0x6a0 Use skb_checksum instead of csum_partial who cannot deal with non-linear SKBs. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: túneles: corrige el acceso fuera de los límites al compilar el error IPv6 PMTU Si el error ICMPv6 se genera a partir de un skb no lineal, obtenemos el siguiente símbolo, ERROR: KASAN: slab-out- fuera de los límites en do_csum+0x220/0x240 Lectura de tamaño 4 en la dirección ffff88811d402c80 por tarea netperf/820 CPU: 0 PID: 820 Comm: netperf Not tainted 6.8.0-rc1+ #543 ... kasan_report+0xd8/0x110 do_csum+0x220 /0x240 csum_partial+0xc/0x20 skb_tunnel_check_pmtu+0xeb9/0x3280 vxlan_xmit_one+0x14c2/0x4080 vxlan_xmit+0xf61/0x5c00 dev_hard_start_xmit+0xfb/0x510 __dev_queue_xmit+0x7cd/0x32 a0 br_dev_queue_push_xmit+0x39d/0x6a0 Utilice skb_checksum en lugar de csum_partial, que no puede manejar SKB no lineales. A flaw was found in the Linux kernel. This issue occurs due to the improper handling of non-linear skbs (socket buffers) when calculating checksums for ICMPv6 PMTU error messages.
