In the Linux kernel, the following vulnerability has been resolved: fs/9p: only translate RWX permissions for plain 9P2000 Garbage in plain 9P2000's perm bits is allowed through, which causes it to be able to set (among others) the suid bit. This was presumably not the intent since the unix extended bits are handled explicitly and conditionally on .u. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: fs/9p: solo traduce permisos RWX para 9P2000 simple. Se permite el paso de basura en bits permanentes de 9P2000 simple, lo que hace que pueda establecer (entre otros) el bit suid. Probablemente esta no era la intención, ya que los bits extendidos de Unix se manejan explícita y condicionalmente en .u. • https://git.kernel.org/stable/c/e90bc596a74bb905e0a45bf346038c3f9d1e868d https://git.kernel.org/stable/c/df1962a199783ecd66734d563caf0fedecf08f96 https://git.kernel.org/stable/c/5a605930e19f451294bd838754f7d66c976a8a2c https://git.kernel.org/stable/c/ad4f65328661392de74e3608bb736fedf3b67e32 https://git.kernel.org/stable/c/ca9b5c81f0c918c63d73d962ed8a8e231f840bc8 https://git.kernel.org/stable/c/e55c601af3b1223a84f9f27f9cdbd2af5e203bf3 https://git.kernel.org/stable/c/157d468e34fdd3cb1ddc07c2be32fb3b02826b02 https://git.kernel.org/stable/c/cd25e15e57e68a6b18dc9323047fe9c68 •
CVSS: 7.1EPSS: 0%CPEs: 8EXPL: 0CVE-2024-36960 – drm/vmwgfx: Fix invalid reads in fence signaled events
https://notcve.org/view.php?id=CVE-2024-36960
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fix invalid reads in fence signaled events Correctly set the length of the drm_event to the size of the structure that's actually used. The length of the drm_event was set to the parent structure instead of to the drm_vmw_event_fence which is supposed to be read. drm_read uses the length parameter to copy the event to the user space thus resuling in oob reads. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/vmwgfx: corrige lecturas no válidas en eventos señalizados de valla establezca correctamente la longitud de drm_event al tamaño de la estructura que realmente se utiliza. La longitud de drm_event se configuró en la estructura principal en lugar de en drm_vmw_event_fence que se supone debe leerse. drm_read usa el parámetro de longitud para copiar el evento al espacio del usuario, lo que resulta en lecturas oob. This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of vmw fence events. • https://git.kernel.org/stable/c/8b7de6aa84682a3396544fd88cd457f95484573a https://git.kernel.org/stable/c/2f527e3efd37c7c5e85e8aa86308856b619fa59f https://git.kernel.org/stable/c/cef0962f2d3e5fd0660c8efb72321083a1b531a9 https://git.kernel.org/stable/c/3cd682357c6167f636aec8ac0efaa8ba61144d36 https://git.kernel.org/stable/c/b7bab33c4623c66e3398d5253870d4e88c52dfc0 https://git.kernel.org/stable/c/0dbfc73670b357456196130551e586345ca48e1b https://git.kernel.org/stable/c/7b5fd3af4a250dd0a2a558e07b43478748eb5d22 https://git.kernel.org/stable/c/deab66596dfad14f1c54eeefdb7242834 • CWE-125: Out-of-bounds Read •

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-v2: Check for non-NULL vCPU in vgic_v2_parse_attr() vgic_v2_parse_attr() is responsible for finding the vCPU that matches the user-provided CPUID, which (of course) may not be valid. If the ID is invalid, kvm_get_vcpu_by_id() returns NULL, which isn't handled gracefully. Similar to the GICv3 uaccess flow, check that kvm_get_vcpu_by_id() actually returns something and fail the ioctl if not. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: KVM: arm64: vgic-v2: Verifique vCPU que no sea NULL en vgic_v2_parse_attr() vgic_v2_parse_attr() es responsable de encontrar la vCPU que coincida con el CPUID proporcionado por el usuario, que (de curso) puede no ser válido. Si el ID no es válido, kvm_get_vcpu_by_id() devuelve NULL, que no se maneja correctamente.

CVSS: 4.4EPSS: 0%CPEs: 5EXPL: 0CVE-2024-36952 – scsi: lpfc: Move NPIV's transport unregistration to after resource clean up
https://notcve.org/view.php?id=CVE-2024-36952
In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Move NPIV's transport unregistration to after resource clean up There are cases after NPIV deletion where the fabric switch still believes the NPIV is logged into the fabric. This occurs when a vport is unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the fabric. Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including the fabric D_ID, removes the last ndlp reference and frees the ndlp rport object. This sometimes causes the race condition where the final DA_ID and LOGO are skipped from being sent to the fabric switch. Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID and LOGO are sent. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: scsi: lpfc: Mover la anulación del registro de transporte de NPIV a después de la limpieza de recursos. Hay casos después de la eliminación de NPIV en los que el conmutador de tejido todavía cree que el NPIV está registrado en el tejido. • https://git.kernel.org/stable/c/f2c7f029051edc4b394bb48edbe2297575abefe0 https://git.kernel.org/stable/c/0936809d968ecf81e0726fbd02ff2a5732d960c3 https://git.kernel.org/stable/c/76337eb8daee32bcc67742efab3168ed4ca299d0 https://git.kernel.org/stable/c/718602cd15f4c5710850090ea3066a89eeb46278 https://git.kernel.org/stable/c/4ddf01f2f1504fa08b766e8cfeec558e9f8eef6c https://access.redhat.com/security/cve/CVE-2024-36952 https://bugzilla.redhat.com/show_bug.cgi?id=2284598 • CWE-459: Incomplete Cleanup •
