https://notcve.org/view.php?id=CVE-2024-49892
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Initialize get_bytes_per_element's default to 1 Variables, used as denominators and maybe not assigned to other values, should not be 0. bytes_per_element_y & bytes_per_element_c are initialized by get_bytes_per_element() which should never return 0. This fixes 10 DIVIDE_BY_ZERO issues reported by Coverity. • https://git.kernel.org/stable/c/8f0abb39c16e719129de10596b3ae3363fa178b4 https://git.kernel.org/stable/c/f921335123f6620c3dce5c96fbb95f18524a021c https://git.kernel.org/stable/c/1f9f8186e239222f1c8d3dd73bf3bc6ae86c5e76 https://git.kernel.org/stable/c/a23d6029e730f8a151b1a34afb169baac1274583 https://git.kernel.org/stable/c/c7630935d9a4986e8c0ed91658a781b7a77d73f7 https://git.kernel.org/stable/c/bc00d211da4ffad5314a2043b50bdc8ff8a33724 https://git.kernel.org/stable/c/3334ab72cbba55a632f24579cd47c4a4e5e69cda https://git.kernel.org/stable/c/4067f4fa0423a89fb19a30b57231b384d •

https://notcve.org/view.php?id=CVE-2024-49891
In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Validate hdwq pointers before dereferencing in reset/errata paths When the HBA is undergoing a reset or is handling an errata event, NULL ptr dereference crashes may occur in routines such as lpfc_sli_flush_io_rings(), lpfc_dev_loss_tmo_callbk(), or lpfc_abort_handler(). Add NULL ptr checks before dereferencing hdwq pointers that may have been freed due to operations colliding with a reset or errata event handler. • https://git.kernel.org/stable/c/99a801e2fca39a6f31e543fc3383058a8955896f https://git.kernel.org/stable/c/fd665c8dbdb19548965b0ae80c490de00e906366 https://git.kernel.org/stable/c/2be1d4f11944cd6283cb97268b3e17c4424945ca •

CVSS: -EPSS: 0%CPEs: 7EXPL: 0CVE-2024-49889 – ext4: avoid use-after-free in ext4_ext_show_leaf()
https://notcve.org/view.php?id=CVE-2024-49889
In the Linux kernel, the following vulnerability has been resolved: ext4: avoid use-after-free in ext4_ext_show_leaf() In ext4_find_extent(), path may be freed by error or be reallocated, so using a previously saved *ppath may have been freed and thus may trigger use-after-free, as follows: ext4_split_extent path = *ppath; ext4_split_extent_at(ppath) path = ext4_find_extent(ppath) ext4_split_extent_at(ppath) // ext4_find_extent fails to free path // but zeroout succeeds ext4_ext_show_leaf(inode, path) eh = path[depth].p_hdr // path use-after-free !!! Similar to ext4_split_extent_at(), we use *ppath directly as an input to ext4_ext_show_leaf(). Fix a spelling error by the way. Same problem in ext4_ext_handle_unwritten_extents(). Since 'path' is only used in ext4_ext_show_leaf(), remove 'path' and use *ppath directly. This issue is triggered only when EXT_DEBUG is defined and therefore does not affect functionality. • https://git.kernel.org/stable/c/b0cb4561fc4284d04e69c8a66c8504928ab2484e https://git.kernel.org/stable/c/4999fed877bb64e3e7f9ab9996de2ca983c41928 https://git.kernel.org/stable/c/2eba3b0cc5b8de624918d21f32b5b8db59a90b39 https://git.kernel.org/stable/c/34b2096380ba475771971a778a478661a791aa15 https://git.kernel.org/stable/c/8b114f2cc7dd5d36729d040b68432fbd0f0a8868 https://git.kernel.org/stable/c/d483c7cc1796bd6a80e7b3a8fd494996260f6b67 https://git.kernel.org/stable/c/4e2524ba2ca5f54bdbb9e5153bea00421ef653f5 •
