CVSS: -EPSS: 0%CPEs: 7EXPL: 0CVE-2024-49895 – drm/amd/display: Fix index out of bounds in DCN30 degamma hardware format translation
https://notcve.org/view.php?id=CVE-2024-49895
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix index out of bounds in DCN30 degamma hardware format translation This commit addresses a potential index out of bounds issue in the `cm3_helper_translate_curve_to_degamma_hw_format` function in the DCN30 color management module. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds, the function returns false to indicate an error.

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check stream_status before it is used [WHAT & HOW] dc_state_get_stream_status can return null, and therefore null must be checked before stream_status is used. This fixes 1 NULL_RETURNS issue reported by Coverity. • https://git.kernel.org/stable/c/4914c8bfee1843fae046a12970b6f178e6642659 https://git.kernel.org/stable/c/58a8ee96f84d2c21abb85ad8c22d2bbdf59bd7a9 •

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.

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/5873aa7f814754085d418848b2089ef406a02dd0 https://git.kernel.org/stable/c/232a138bd843d48cb2368f604646d990db7640f3 https://git.kernel.org/stable/c/99a801e2fca39a6f31e543fc3383058a8955896f https://git.kernel.org/stable/c/fd665c8dbdb19548965b0ae80c490de00e906366 https://git.kernel.org/stable/c/2be1d4f11944cd6283cb97268b3e17c4424945ca •
