CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-35994 – firmware: qcom: uefisecapp: Fix memory related IO errors and crashes
https://notcve.org/view.php?id=CVE-2024-35994
In the Linux kernel, the following vulnerability has been resolved: firmware: qcom: uefisecapp: Fix memory related IO errors and crashes It turns out that while the QSEECOM APP_SEND command has specific fields for request and response buffers, uefisecapp expects them both to be in a single memory region. Failure to adhere to this has (so far) resulted in either no response being written to the response buffer (causing an EIO to be emitted down the line), the SCM call to fail with EINVAL (i.e., directly from TZ/firmware), or the device to be hard-reset. While this issue can be triggered deterministically, in the current form it seems to happen rather sporadically (which is why it has gone unnoticed during earlier testing). This is likely due to the two kzalloc() calls (for request and response) being directly after each other. Which means that those likely return consecutive regions most of the time, especially when not much else is going on in the system. Fix this by allocating a single memory region for both request and response buffers, properly aligning both structs inside it. This unfortunately also means that the qcom_scm_qseecom_app_send() interface needs to be restructured, as it should no longer map the DMA regions separately. • https://git.kernel.org/stable/c/759e7a2b62eb3ef3c93ffeb5cca788a09627d7d9 https://git.kernel.org/stable/c/dd22b34fb53cb04b13b2f5eee5c9200bb091fc88 https://git.kernel.org/stable/c/ed09f81eeaa8f9265e1787282cb283f10285c259 •
CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-35993 – mm: turn folio_test_hugetlb into a PageType
https://notcve.org/view.php?id=CVE-2024-35993
In the Linux kernel, the following vulnerability has been resolved: mm: turn folio_test_hugetlb into a PageType The current folio_test_hugetlb() can be fooled by a concurrent folio split into returning true for a folio which has never belonged to hugetlbfs. This can't happen if the caller holds a refcount on it, but we have a few places (memory-failure, compaction, procfs) which do not and should not take a speculative reference. Since hugetlb pages do not use individual page mapcounts (they are always fully mapped and use the entire_mapcount field to record the number of mappings), the PageType field is available now that page_mapcount() ignores the value in this field. In compaction and with CONFIG_DEBUG_VM enabled, the current implementation can result in an oops, as reported by Luis. This happens since 9c5ccf2db04b ("mm: remove HUGETLB_PAGE_DTOR") effectively added some VM_BUG_ON() checks in the PageHuge() testing path. [willy@infradead.org: update vmcoreinfo] Link: https://lkml.kernel.org/r/ZgGZUvsdhaT1Va-T@casper.infradead.org En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mm: convierte folio_test_hugetlb en un PageType. El folio_test_hugetlb() actual puede ser engañado por una división de folio concurrente y devuelve verdadero para un folio que nunca ha pertenecido a hugetlbfs. Esto no puede suceder si la persona que llama tiene un recuento sobre él, pero tenemos algunos lugares (fallo de memoria, compactación, procfs) que no toman ni deben tomar una referencia especulativa. Dado que las páginas de Hugetlb no usan recuentos de mapas de páginas individuales (siempre están completamente asignadas y usan el campo Whole_mapcount para registrar el número de asignaciones), el campo PageType está disponible ahora que page_mapcount() ignora el valor en este campo. • https://git.kernel.org/stable/c/9c5ccf2db04b8d7c3df363fdd4856c2b79ab2c6a https://git.kernel.org/stable/c/2431b5f2650dfc47ce782d1ca7b02d6b3916976f https://git.kernel.org/stable/c/9fdcc5b6359dfdaa52a55033bf50e2cedd66eb32 https://git.kernel.org/stable/c/d99e3140a4d33e26066183ff727d8f02f56bec64 •
