CVE-2021-47432 – lib/generic-radix-tree.c: Don't overflow in peek()
https://notcve.org/view.php?id=CVE-2021-47432
In the Linux kernel, the following vulnerability has been resolved: lib/generic-radix-tree.c: Don't overflow in peek() When we started spreading new inode numbers throughout most of the 64 bit inode space, that triggered some corner case bugs, in particular some integer overflows related to the radix tree code. Oops. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: lib/generic-radix-tree.c: No se desborda en peek() Cuando comenzamos a distribuir nuevos números de inodos en la mayor parte del espacio de inodos de 64 bits, eso activó algunas esquinas. errores de casos, en particular algunos desbordamientos de enteros relacionados con el código del árbol de base. Ups. • https://git.kernel.org/stable/c/784d01f9bbc282abb0c5ade5beb98a87f50343ac https://git.kernel.org/stable/c/ec298b958cb0c40d70c68079da933c8f31c5134c https://git.kernel.org/stable/c/aa7f1827953100cdde0795289a80c6c077bfe437 https://git.kernel.org/stable/c/9492261ff2460252cf2d8de89cdf854c7e2b28a0 https://access.redhat.com/security/cve/CVE-2021-47432 https://bugzilla.redhat.com/show_bug.cgi?id=2282366 •

CVE-2023-52744 – RDMA/irdma: Fix potential NULL-ptr-dereference
https://notcve.org/view.php?id=CVE-2023-52744
In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix potential NULL-ptr-dereference in_dev_get() can return NULL which will cause a failure once idev is dereferenced in in_dev_for_each_ifa_rtnl(). This patch adds a check for NULL value in idev beforehand. Found by Linux Verification Center (linuxtesting.org) with SVACE. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: RDMA/irdma: se corrige una posible referencia NULL-ptr-dereference in_dev_get() que puede devolver NULL, lo que provocará una falla una vez que se elimine la referencia a idev en in_dev_for_each_ifa_rtnl(). Este parche agrega una verificación previa del valor NULL en idev.

CVE-2023-52743 – ice: Do not use WQ_MEM_RECLAIM flag for workqueue
https://notcve.org/view.php?id=CVE-2023-52743
In the Linux kernel, the following vulnerability has been resolved: ice: Do not use WQ_MEM_RECLAIM flag for workqueue When both ice and the irdma driver are loaded, a warning in check_flush_dependency is being triggered. This is due to ice driver workqueue being allocated with the WQ_MEM_RECLAIM flag and the irdma one is not. According to kernel documentation, this flag should be set if the workqueue will be involved in the kernel's memory reclamation flow. Since it is not, there is no need for the ice driver's WQ to have this flag set so remove it.
