https://notcve.org/view.php?id=CVE-2024-49850
In the Linux kernel, the following vulnerability has been resolved: bpf: correctly handle malformed BPF_CORE_TYPE_ID_LOCAL relos In case of malformed relocation record of kind BPF_CORE_TYPE_ID_LOCAL referencing a non-existing BTF type, function bpf_core_calc_relo_insn would cause a null pointer deference. Fix this by adding a proper check upper in call stack, as malformed relocation records could be passed from user space. Simplest reproducer is a program: r0 = 0 exit With a single relocation record: .insn_off = 0, /* patch first instruction */ .type_id = 100500, /* this type id does not exist */ .access_str_off = 6, /* offset of string "0" */ .kind = BPF_CORE_TYPE_ID_LOCAL, See the link for original reproducer or next commit for a test case. • https://git.kernel.org/stable/c/74753e1462e77349525daf9eb60ea21ed92d3a97 https://git.kernel.org/stable/c/dc7ce14f00bcd50641f2110b7a32aa6552e0780f https://git.kernel.org/stable/c/2288b54b96dcb55bedebcef3572bb8821fc5e708 https://git.kernel.org/stable/c/584cd3ff792e1edbea20b2a7df55897159b0be3e https://git.kernel.org/stable/c/e7e9c5b2dda29067332df2a85b0141a92b41f218 https://git.kernel.org/stable/c/3d2786d65aaa954ebd3fcc033ada433e10da21c4 •

https://notcve.org/view.php?id=CVE-2024-47757
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix potential oob read in nilfs_btree_check_delete() The function nilfs_btree_check_delete(), which checks whether degeneration to direct mapping occurs before deleting a b-tree entry, causes memory access outside the block buffer when retrieving the maximum key if the root node has no entries. This does not usually happen because b-tree mappings with 0 child nodes are never created by mkfs.nilfs2 or nilfs2 itself. However, it can happen if the b-tree root node read from a device is configured that way, so fix this potential issue by adding a check for that case. • https://git.kernel.org/stable/c/17c76b0104e4a6513983777e1a17e0297a12b0c4 https://git.kernel.org/stable/c/d20674f31626e0596ae4c1d9401dfb6739b81b58 https://git.kernel.org/stable/c/c4f8554996e8ada3be872dfb8f60e93bcf15fb27 https://git.kernel.org/stable/c/a8abfda768b9f33630cfbc4af6c4214f1e5681b0 https://git.kernel.org/stable/c/257f9e5185eb6de83377caea686c306e22e871f2 https://git.kernel.org/stable/c/a33e967b681e088a125b979975c93e3453e686cd https://git.kernel.org/stable/c/c4cbcc64bb31e67e02940ce060cc77f7180564cf https://git.kernel.org/stable/c/f9c96351aa6718b42a9f42eaf7adce035 •

https://notcve.org/view.php?id=CVE-2024-47756
In the Linux kernel, the following vulnerability has been resolved: PCI: keystone: Fix if-statement expression in ks_pcie_quirk() This code accidentally uses && where || was intended. It potentially results in a NULL dereference. Thus, fix the if-statement expression to use the correct condition.
