CVE-2024-43856 – dma: fix call order in dmam_free_coherent
https://notcve.org/view.php?id=CVE-2024-43856
17 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: dma: fix call order in dmam_free_coherent dmam_free_coherent() frees a DMA allocation, which makes the freed vaddr available for reuse, then calls devres_destroy() to remove and free the data structure used to track the DMA allocation. Between the two calls, it is possible for a concurrent task to make an allocation with the same vaddr and add it to the devres list. If this happens, there will be two entries in the devres list with the same... • https://git.kernel.org/stable/c/9ac7849e35f705830f7b016ff272b0ff1f7ff759 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2024-43854 – block: initialize integrity buffer to zero before writing it to media
https://notcve.org/view.php?id=CVE-2024-43854
17 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: block: initialize integrity buffer to zero before writing it to media Metadata added by bio_integrity_prep is using plain kmalloc, which leads to random kernel memory being written media. For PI metadata this is limited to the app tag that isn't used by kernel generated metadata, but for non-PI metadata the entire buffer leaks kernel memory. Fix this by adding the __GFP_ZERO flag to allocations for writes. In the Linux kernel, the following... • https://git.kernel.org/stable/c/7ba1ba12eeef0aa7113beb16410ef8b7c748e18b • CWE-401: Missing Release of Memory after Effective Lifetime •

17 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: Prevent UAF in proc_cpuset_show() An UAF can happen when /proc/cpuset is read as reported in [1]. This can be reproduced by the following methods: 1.add an mdelay(1000) before acquiring the cgroup_lock In the cgroup_path_ns function. 2.$cat /proc/

17 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: lib: objagg: Fix general protection fault The library supports aggregation of objects into other objects only if the parent object does not have a parent itself. That is, nesting is not supported. Aggregation happens in two cases: Without and with hints, where hints are a pre-computed recommendation on how to aggregate the provided objects. Nesting is not possible in the first case due to a check that prevents it, but in the second case the... • https://git.kernel.org/stable/c/9069a3817d82b01b3a55da382c774e3575946130 •
CVE-2024-43841 – wifi: virt_wifi: avoid reporting connection success with wrong SSID

CVE-2024-43839 – bna: adjust 'name' buf size of bna_tcb and bna_ccb structures

17 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: bna: adjust 'name' buf size of bna_tcb and bna_ccb structures To have enough space to write all possible sprintf() args. Currently 'name' size is 16, but the first '%s' specifier may already need at least 16 characters, since 'bnad->netdev->name' is used there.
