    net: atlantic: eliminate double free in error handling logic

    In the Linux kernel, the following vulnerability has been resolved: net: atlantic: eliminate double free in error handling logic Driver has a logic leak in ring data allocation/free, where aq_ring_free could be called multiple times on same ring, if system is under stress and got memory allocation error. Ring pointer was used as an indicator of failure, but this is not correct since only ring data is allocated/deallocated. Ring itself is an array member. Changing ring allocation functions to return error code directly. This simplifies error handling and eliminates aq_ring_free on higher layer.

    In the Linux kernel, the following vulnerability has been resolved: wifi: libertas: fix some memleaks in lbs_allocate_cmd_buffer() In the for statement of lbs_allocate_cmd_buffer(), if the allocation of cmdarray[i].cmdbuf fails, both cmdarray and cmdarray[i].cmdbuf needs to be freed. Otherwise, there will be memleaks in lbs_allocate_cmd_buffer().

    usb: gadget: ncm: Fix handling of zero block length packets

    In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ncm: Fix handling of zero block length packets While connecting to a Linux host with CDC_NCM_NTB_DEF_SIZE_TX set to 65536, it has been observed that we receive short packets, which come at interval of 5-10 seconds sometimes and have block length zero but still contain 1-2 valid datagrams present. According to the NCM spec: "If wBlockLength = 0x0000, the block is terminated by a short packet. In this case, the USB transfer must still be shorter than dwNtbInMaxSize or dwNtbOutMaxSize.

    vt: fix unicode buffer corruption when deleting characters

    In the Linux kernel, the following vulnerability has been resolved: vt: fix unicode buffer corruption when deleting characters This is the same issue that was fixed for the VGA text buffer in commit 39cdb68c64d8 ("vt: fix memory overlapping when deleting chars in the buffer"). The cure is also the same i.e. replace memcpy() with memmove() due to the overlaping buffers.

    ubifs: Set page uptodate in the correct place

    In the Linux kernel, the following vulnerability has been resolved: ubifs: Set page uptodate in the correct place Page cache reads are lockless, so setting the freshly allocated page uptodate before we've overwritten it with the data it's supposed to have in it will allow a simultaneous reader to see old data. Move the call to SetPageUptodate into ubifs_write_end(), which is after we copied the new data into the page.

    soc: fsl: qbman: Use raw spinlock for cgr_lock

    In the Linux kernel, the following vulnerability has been resolved: soc: fsl: qbman: Use raw spinlock for cgr_lock smp_call_function always runs its callback in hard IRQ context, even on PREEMPT_RT, where spinlocks can sleep. So we need to use a raw spinlock for cgr_lock to ensure we aren't waiting on a sleeping task. Although this bug has existed for a while, it was not apparent until commit ef2a8d5478b9 ("net: dpaa: Adjust queue depth on rate change") which invokes smp_call_function_single via qman_update_cgr_safe every time a link goes up or down.

    In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: amdgpu_ttm_gart_bind set gtt bound flag Otherwise after the GTT bo is released, the GTT and gart space is freed but amdgpu_ttm_backend_unbind will not clear the gart page table entry and leave valid mapping entry pointing to the stale system page. Then if GPU access the gart address mistakely, it will read undefined value instead page fault, harder to debug and reproduce the real issue.

    fs/aio: Check IOCB_AIO_RW before the struct aio_kiocb conversion

    In the Linux kernel, the following vulnerability has been resolved: fs/aio: Check IOCB_AIO_RW before the struct aio_kiocb conversion The first kiocb_set_cancel_fn() argument may point at a struct kiocb that is not embedded inside struct aio_kiocb. With the current code, depending on the compiler, the req->ki_ctx read happens either before the IOCB_AIO_RW test or after that test. Move the req->ki_ctx read such that it is guaranteed that the IOCB_AIO_RW test happens first.

    PCI/PM: Drain runtime-idle callbacks before driver removal

    In the Linux kernel, the following vulnerability has been resolved: PCI/PM: Drain runtime-idle callbacks before driver removal A race condition between the .runtime_idle() callback and the .remove() callback in the rtsx_pcr PCI driver leads to a kernel crash due to an unhandled page fault [1]. The problem is that rtsx_pci_runtime_idle() is not expected to be running after pm_runtime_get_sync() has been called, but the latter doesn't really guarantee that. It only guarantees that the suspend and resume callbacks will not be running when it returns. However, if a .runtime_idle() callback is already running when pm_runtime_get_sync() is cal

    ext4: fix corruption during on-line resize

    In the Linux kernel, the following vulnerability has been resolved: ext4: fix corruption during on-line resize We observed a corruption during on-line resize of a file system that is larger than 16 TiB with 4k block size. With having more then 2^32 blocks resize_inode is turned off by default by mke2fs. The issue can be reproduced on a smaller file system for convenience by explicitly turning off resize_inode. An on-line resize across an 8 GiB boundary (the size of a meta block group in this setup) then leads to a corruption: dev=/dev/<some_dev> # should be >= 16 GiB mkdir -p /corruption /sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode

    In the Linux kernel, the following vulnerability has been resolved: soc: fsl: qbman: Always disable interrupts when taking cgr_lock smp_call_function_single disables IRQs when executing the callback. To prevent deadlocks, we must disable IRQs when taking cgr_lock elsewhere. This is already done by qman_update_cgr and qman_delete_cgr; fix the other lockers.

    KVM: x86: Mark target gfn of emulated atomic instruction as dirty

    In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Mark target gfn of emulated atomic instruction as dirty When emulating an atomic access on behalf of the guest, mark the target gfn dirty if the CMPXCHG by KVM is attempted and doesn't fault. This fixes a bug where KVM effectively corrupts guest memory during live migration by writing to guest memory without informing userspace that the page is dirty. Marking the page dirty got unintentionally dropped when KVM's emulated CMPXCHG was converted to do a user access. Before that, KVM explicitly mapped the guest page into kernel memory, and marked the page dirty dur

This eventually ends up in platform_get_resource_byname in the call stack, where it causes a null pointer in strcmp. if (type == resource_type(r) && !strcmp(r->name, name)) It should have been replaced with devm_platform_ioremap_resource.
