In the Linux kernel, the following vulnerability has been resolved: Bluetooth: qca: fix NULL-deref on non-serdev setup Qualcomm ROME controllers can be registered from the Bluetooth line discipline and in this case the HCI UART serdev pointer is NULL. Add the missing sanity check to prevent a NULL-pointer dereference when setup() is called for a non-serdev controller. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Bluetooth: qca: corrige NULL-deref en configuración sin serdev. Los controladores Qualcomm ROME se pueden registrar desde la disciplina de línea Bluetooth y en este caso el puntero HCI UART serdev es NULL. Agregue la verificación de sanidad que falta para evitar una desreferencia del puntero NULL cuando se llama a setup() para un controlador que no es serdev. • https://git.kernel.org/stable/c/e9b3e5b8c65733f626a7ee919c4bc895b51d7bb2 https://git.kernel.org/stable/c/67459f1a707aae6d590454de07956c2752e21ea4 https://git.kernel.org/stable/c/bec4d4c6fa5c6526409f582e4f31144e20c86c21 https://git.kernel.org/stable/c/7ddb9de6af0f1c71147785b12fd7c8ec3f06cc86 •

CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2024-35847 – irqchip/gic-v3-its: Prevent double free on error
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 •
