https://notcve.org/view.php?id=CVE-2024-35847
In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3-its: Prevent double free on error The error handling path in its_vpe_irq_domain_alloc() causes a double free when its_vpe_init() fails after successfully allocating at least one interrupt. This happens because its_vpe_irq_domain_free() frees the interrupts along with the area bitmap and the vprop_page and its_vpe_irq_domain_alloc() subsequently frees the area bitmap and the vprop_page again. Fix this by unconditionally invoking its_vpe_irq_domain_free() which handles all cases correctly and by removing the bitmap/vprop_page freeing from its_vpe_irq_domain_alloc(). [ tglx: Massaged change log ] En el kernel de Linux, se resolvió la siguiente vulnerabilidad: irqchip/gic-v3-its: Evitar el double free en caso de error. La ruta de manejo de errores en its_vpe_irq_domain_alloc() provoca un double free cuando its_vpe_init() falla después de asignar exitosamente al menos una interrupción. Esto sucede porque its_vpe_irq_domain_free() libera las interrupciones junto con el mapa de bits del área y la vprop_page y its_vpe_irq_domain_alloc() posteriormente libera nuevamente el mapa de bits del área y la vprop_page. Solucione este problema invocando incondicionalmente its_vpe_irq_domain_free() que maneja todos los casos correctamente y eliminando el mapa de bits/vprop_page que se libera de its_vpe_irq_domain_alloc(). • https://git.kernel.org/stable/c/7d75bbb4bc1ad90386776459d37e4ddfe605671e https://git.kernel.org/stable/c/f5417ff561b8ac9a7e53c747b8627a7ab58378ae https://git.kernel.org/stable/c/b72d2b1448b682844f995e660b77f2a1fabc1662 https://git.kernel.org/stable/c/aa44d21574751a7d6bca892eb8e0e9ac68372e52 https://git.kernel.org/stable/c/5dbdbe1133911ca7d8466bb86885adec32ad9438 https://git.kernel.org/stable/c/dd681710ab77c8beafe2e263064cb1bd0e2d6ca9 https://git.kernel.org/stable/c/03170e657f62c26834172742492a8cb8077ef792 https://git.kernel.org/stable/c/5b012f77abde89bf0be8a0547636184fe •

https://notcve.org/view.php?id=CVE-2024-35846
In the Linux kernel, the following vulnerability has been resolved: mm: zswap: fix shrinker NULL crash with cgroup_disable=memory Christian reports a NULL deref in zswap that he bisected down to the zswap shrinker. The issue also cropped up in the bug trackers of libguestfs [1] and the Red Hat bugzilla [2]. The problem is that when memcg is disabled with the boot time flag, the zswap shrinker might get called with sc->memcg == NULL. This is okay in many places, like the lruvec operations. But it crashes in memcg_page_state() - which is only used due to the non-node accounting of cgroup's the zswap memory to begin with. Nhat spotted that the memcg can be NULL in the memcg-disabled case, and I was then able to reproduce the crash locally as well.

CVSS: 6.8EPSS: 0%CPEs: 2EXPL: 0CVE-2024-35843 – iommu/vt-d: Use device rbtree in iopf reporting path
https://notcve.org/view.php?id=CVE-2024-35843
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Use device rbtree in iopf reporting path The existing I/O page fault handler currently locates the PCI device by calling pci_get_domain_bus_and_slot(). This function searches the list of all PCI devices until the desired device is found. To improve lookup efficiency, replace it with device_rbtree_find() to search the device within the probed device rbtree. The I/O page fault is initiated by the device, which does not have any synchronization mechanism with the software to ensure that the device stays in the probed device tree. Theoretically, a device could be released by the IOMMU subsystem after device_rbtree_find() and before iopf_get_dev_fault_param(), which would cause a use-after-free problem. Add a mutex to synchronize the I/O page fault reporting path and the IOMMU release device path. This lock doesn't introduce any performance overhead, as the conflict between I/O page fault reporting and device releasing is very rare. • https://git.kernel.org/stable/c/3d39238991e745c5df85785604f037f35d9d1b15 https://git.kernel.org/stable/c/def054b01a867822254e1dda13d587f5c7a99e2a https://access.redhat.com/security/cve/CVE-2024-35843 https://bugzilla.redhat.com/show_bug.cgi?id=2281276 • CWE-416: Use After Free •
