In the Linux kernel, the following vulnerability has been resolved: kdb: Fix buffer overflow during tab-complete Currently, when the user attempts symbol completion with the Tab key, kdb will use strncpy() to insert the completed symbol into the command buffer. Unfortunately it passes the size of the source buffer rather than the destination to strncpy() with predictably horrible results. ... En el kernel de Linux, se resolvió la siguiente vulnerabilidad: kdb: corrige el desbordamiento del búfer durante la finalización de tabulación Actualmente, cuando el usuario intenta completar el símbolo con la tecla Tab, kdb usará strncpy() para insertar el símbolo completado en el búfer de comando. • https://git.kernel.org/stable/c/fb824a99e148ff272a53d71d84122728b5f00992 https://git.kernel.org/stable/c/ddd2972d8e2dee3b33e8121669d55def59f0be8a https://git.kernel.org/stable/c/cfdc2fa4db57503bc6d3817240547c8ddc55fa96 https://git.kernel.org/stable/c/f636a40834d22e5e3fc748f060211879c056cd33 https://git.kernel.org/stable/c/33d9c814652b971461d1e30bead6792851c209e7 https://git.kernel.org/stable/c/107e825cc448b7834b31e8b1b3cf0f57426d46d5 https://git.kernel.org/stable/c/f694da720dcf795dc3eb97bf76d220213f76aaa7 https://git.kernel.org/stable/c/e9730744bf3af04cda23799029342aa3c • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-121: Stack-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2024-39479
In the Linux kernel, the following vulnerability has been resolved: drm/i915/hwmon: Get rid of devm When both hwmon and hwmon drvdata (on which hwmon depends) are device managed resources, the expectation, on device unbind, is that hwmon will be released before drvdata. ... Which means that we have a uaf if hwmon sysfs is accessed when drvdata has been released but hwmon hasn't. The only way out of this seems to be do get rid of devm_ and release/free everything explicitly during device unbind. v2: Change commit message and other minor code changes v3: Cleanup from i915_hwmon_register on error (Armin Wolf) v4: Eliminate potential static analyzer warning (Rodrigo) Eliminate fetch_and_zero (Jani) v5: Restore previous logic for ddat_gt->hwmon_dev error return (Andi) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/i915/hwmon: deshacerse de devm Cuando tanto hwmon como hwmon drvdata (del cual depende hwmon) son recursos administrados por el dispositivo, la expectativa, al desvincular el dispositivo, es que hwmon publicarse antes que drvdata. • https://git.kernel.org/stable/c/cfa73607eb21a4ce1d6294a2c5733628897b48a2 https://git.kernel.org/stable/c/ce5a22d22db691d14516c3b8fdbf69139eb2ea8f https://git.kernel.org/stable/c/5bc9de065b8bb9b8dd8799ecb4592d0403b54281 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2024-39477
In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: do not call vma_add_reservation upon ENOMEM sysbot reported a splat [1] on __unmap_hugepage_range(). This is because vma_needs_reservation() can return -ENOMEM if allocate_file_region_entries() fails to allocate the file_region struct for the reservation. Check for that and do not call vma_add_reservation() if that is the case, otherwise region_abort() and region_del() will see that we do not have any file_regions. If we detect that vma_needs_reservation() returned -ENOMEM, we clear the hugetlb_restore_reserve flag as if this reservation was still consumed, so free_huge_folio() will not increment the resv count.
