https://notcve.org/view.php?id=CVE-2024-47723
In the Linux kernel, the following vulnerability has been resolved: jfs: fix out-of-bounds in dbNextAG() and diAlloc() In dbNextAG() , there is no check for the case where bmp->db_numag is greater or same than MAXAG due to a polluted image, which causes an out-of-bounds. Therefore, a bounds check should be added in dbMount(). And in dbNextAG(), a check for the case where agpref is greater than bmp->db_numag should be added, so an out-of-bounds exception should be prevented. Additionally, a check for the case where agno is greater or same than MAXAG should be added in diAlloc() to prevent out-of-bounds. • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 https://git.kernel.org/stable/c/d1017d2a0f3f16dc1db5120e7ddbe7c6680425b0 https://git.kernel.org/stable/c/5ad6284c8d433f8a213111c5c44ead4d9705b622 https://git.kernel.org/stable/c/0338e66cba272351ca9d7d03f3628e390e70963b https://git.kernel.org/stable/c/ead82533278502428883085a787d5a00f15e5eb9 https://git.kernel.org/stable/c/6ce8b6ab44a8b5918c0ee373d4ad19d19017931b https://git.kernel.org/stable/c/c1ba4b8ca799ff1d99d01f37d7ccb7d5ba5533d2 https://git.kernel.org/stable/c/128d5cfdcf844cb690c9295a3a1c1114c •

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check link_res->hpo_dp_link_enc before using it [WHAT & HOW] Functions dp_enable_link_phy and dp_disable_link_phy can pass link_res without initializing hpo_dp_link_enc and it is necessary to check for null before dereferencing.

CVSS: -EPSS: 0%CPEs: 9EXPL: 0CVE-2024-47699 – nilfs2: fix potential null-ptr-deref in nilfs_btree_insert()
https://notcve.org/view.php?id=CVE-2024-47699
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix potential null-ptr-deref in nilfs_btree_insert() Patch series "nilfs2: fix potential issues with empty b-tree nodes". This series addresses three potential issues with empty b-tree nodes that can occur with corrupted filesystem images, including one recently discovered by syzbot. This patch (of 3): If a b-tree is broken on the device, and the b-tree height is greater than 2 (the level of the root node is greater than 1) even if the number of child nodes of the b-tree root is 0, a NULL pointer dereference occurs in nilfs_btree_prepare_insert(), which is called from nilfs_btree_insert(). This is because, when the number of child nodes of the b-tree root is 0, nilfs_btree_do_lookup() does not set the block buffer head in any of path[x].bp_bh, leaving it as the initial value of NULL, but if the level of the b-tree root node is greater than 1, nilfs_btree_get_nonroot_node(), which accesses the buffer memory of path[x].bp_bh, is called. Fix this issue by adding a check to nilfs_btree_root_broken(), which performs sanity checks when reading the root node from the device, to detect this inconsistency. Thanks to Lizhi Xu for trying to solve the bug and clarifying the cause early on. • https://git.kernel.org/stable/c/17c76b0104e4a6513983777e1a17e0297a12b0c4 https://git.kernel.org/stable/c/2b78e9df10fb7f4e9d3d7a18417dd72fbbc1dfd0 https://git.kernel.org/stable/c/1d94dbdfbb64cc48d10dec65cc3c4fbf2497b343 https://git.kernel.org/stable/c/24bf40740a3da6b4056721da34997ae6938f3da1 https://git.kernel.org/stable/c/73d23ecf234b7a6d47fb883f2dabe10e3230b31d https://git.kernel.org/stable/c/f68523e0f26faade18833fbef577a4295d8e2c94 https://git.kernel.org/stable/c/21839b6fbc3c41b3e374ecbdb0cabbbb2c53cf34 https://git.kernel.org/stable/c/db73500d3f0e558eb642aae1d4782e772 •
