https://notcve.org/view.php?id=CVE-2024-53045
In the Linux kernel, the following vulnerability has been resolved: ASoC: dapm: fix bounds checker error in dapm_widget_list_create The widgets array in the snd_soc_dapm_widget_list has a __counted_by attribute attached to it, which points to the num_widgets variable. This attribute is used in bounds checking, and if it is not set before the array is filled, then the bounds sanitizer will issue a warning or a kernel panic if CONFIG_UBSAN_TRAP is set. This patch sets the size of the widgets list calculated with list_for_each as the initial value for num_widgets as it is used for allocating memory for the array. It is updated with the actual number of added elements after the array is filled. • https://git.kernel.org/stable/c/80e698e2df5ba2124bdeca37f1e589de58a4d514 https://git.kernel.org/stable/c/c549cb66e8de0ba1936fc97a59f0156741d3492a https://git.kernel.org/stable/c/2ef9439f7a19fd3d43b288d38b1c6e55b668a4fe •

In the Linux kernel, the following vulnerability has been resolved: mctp i2c: handle NULL header address daddr can be NULL if there is no neighbour table entry present, in that case the tx packet should be dropped. saddr will usually be set by MCTP core, but check for NULL in case a packet is transmitted by a different protocol. • https://git.kernel.org/stable/c/f5b8abf9fc3dacd7529d363e26fe8230935d65f8 https://git.kernel.org/stable/c/4707893315802a0917231b94cb20cbe50ccbfe03 https://git.kernel.org/stable/c/8e886e44397ba89f6e8da8471386112b4f5b67b7 https://git.kernel.org/stable/c/8c222adadc1612e4f097688875962a28e3f5ab44 https://git.kernel.org/stable/c/01e215975fd80af81b5b79f009d49ddd35976c13 •
