    Bluetooth: MGMT: Protect mgmt_pending list with its own lock

    In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: Protect mgmt_pending list with its own lock This uses a mutex to protect from concurrent access of mgmt_pending list which can cause crashes like: ================================================================== BUG: KASAN: slab-use-after-free in hci_sock_get_channel+0x60/0x68 net/bluetooth/hci_sock.c:91 Read of size 2 at addr ffff0000c48885b2 by task syz.4.334/7318 CPU: 0 UID: 0 PID: 7318 Comm: syz.4.334 Not tainted 6.15.0-rc7-syzkaller-g187899f4124a #0 PREEMPT Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 02/12/2025 Ca

    ALSA: usb-audio: Kill timer properly at removal

    In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Kill timer properly at removal The USB-audio MIDI code initializes the timer, but in a rare case, the driver might be freed without the disconnect call. This leaves the timer in an active state while the assigned object is released via snd_usbmidi_free(), which ends up with a kernel warning when the debug configuration is enabled, as spotted by fuzzer. For avoiding the problem, put timer_shutdown_sync() at snd_usbmidi_free(), so that the timer can be killed properly. While we're at it, replace the existing timer_delete_sync() at the disconnect callback wi

    HID: usbhid: Eliminate recurrent out-of-bounds bug in usbhid_parse()

    In the Linux kernel, the following vulnerability has been resolved: HID: usbhid: Eliminate recurrent out-of-bounds bug in usbhid_parse() Update struct hid_descriptor to better reflect the mandatory and optional parts of the HID Descriptor as per USB HID 1.11 specification. Note: the kernel currently does not parse any optional HID class descriptors, only the mandatory report descriptor. Update all references to member element desc[0] to rpt_desc. Add test to verify bLength and bNumDescriptors values are valid. Replace the for loop with direct access to the mandatory HID class descriptor member for the report descriptor. This eliminates t

    In the Linux kernel, the following vulnerability has been resolved: VMCI: fix race between vmci_host_setup_notify and vmci_ctx_unset_notify During our test, it is found that a warning can be trigger in try_grab_folio as follow: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 1678 at mm/gup.c:147 try_grab_folio+0x106/0x130 Modules linked in: CPU: 0 UID: 0 PID: 1678 Comm: syz.3.31 Not tainted 6.15.0-rc5 #163 PREEMPT(undef) RIP: 0010:try_grab_folio+0x106/0x130 Call Trace: <TASK> follow_huge_pmd+0x240/0x8e0 follow_pmd_mask.constprop.0.isra.0+0x40b/0x5c0 follow_pud_mask.constprop.0.isra.0+0x14a/0x170 follow_

    wifi: iwlwifi: don't warn when if there is a FW error

    In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: don't warn when if there is a FW error iwl_trans_reclaim is warning if it is called when the FW is not alive. But if it is called when there is a pending restart, i.e. after a FW error, there is no need to warn, instead - return silently.

    net: cadence: macb: Fix a possible deadlock in macb_halt_tx.

    In the Linux kernel, the following vulnerability has been resolved: net: cadence: macb: Fix a possible deadlock in macb_halt_tx. There is a situation where after THALT is set high, TGO stays high as well. Because jiffies are never updated, as we are in a context with interrupts disabled, we never exit that loop and have a deadlock. That deadlock was noticed on a sama5d4 device that stayed locked for days. Use retries instead of jiffies so that the timeout really works and we do not have a deadlock anymore.

    drivers/rapidio/rio_cm.c: prevent possible heap overwrite

    In the Linux kernel, the following vulnerability has been resolved: drivers/rapidio/rio_cm.c: prevent possible heap overwrite In riocm_cdev_ioctl(RIO_CM_CHAN_SEND) -> cm_chan_msg_send() -> riocm_ch_send() cm_chan_msg_send() checks that userspace didn't send too much data but riocm_ch_send() failed to check that userspace sent sufficient data. The result is that riocm_ch_send() can write to fields in the rio_ch_chan_hdr which were outside the bounds of the space which cm_chan_msg_send() allocated. Address this by teaching riocm_ch_send() to check that the entire rio_ch_chan_hdr was copied in from userspace.

    net: ch9200: fix uninitialised access during mii_nway_restart

    In the Linux kernel, the following vulnerability has been resolved: net: ch9200: fix uninitialised access during mii_nway_restart In mii_nway_restart() the code attempts to call mii->mdio_read which is ch9200_mdio_read(). ch9200_mdio_read() utilises a local buffer called "buff", which is initialised with control_read(). However "buff" is conditionally initialised inside control_read(): if (err == size) { memcpy(data, buf, size); } If the condition of "err == size" is not met, then "buff" remains uninitialised. Once this happens the uninitialised "buff" is accessed and returned during ch9200_mdio_read():

    mm/hugetlb: fix huge_pmd_unshare() vs GUP-fast race

    In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix huge_pmd_unshare() vs GUP-fast race huge_pmd_unshare() drops a reference on a page table that may have previously been shared across processes, potentially turning it into a normal page table used in another process in which unrelated VMAs can afterwards be installed. If this happens in the middle of a concurrent gup_fast(), gup_fast() could end up walking the page tables of another process. While I don't see any way in which that immediately leads to kernel memory corruption, it is really weird and unexpected. Fix it with an explicit broadcast IPI throug

    mm/hugetlb: unshare page tables during VMA split, not before

    In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: unshare page tables during VMA split, not before Currently, __split_vma() triggers hugetlb page table unsharing through vm_ops->may_split(). This happens before the VMA lock and rmap locks are taken - which is too early, it allows racing VMA-locked page faults in our process and racing rmap walks from other processes to cause page tables to be shared again before we actually perform the split. Fix it by explicitly calling into the hugetlb unshare logic from __split_vma() in the same place where THP splitting also happens. At that point, both the VMA and the r

    KVM: x86/mmu: Treat NX as a valid SPTE bit for NPT

    In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Treat NX as a valid SPTE bit for NPT Treat the NX bit as valid when using NPT, as KVM will set the NX bit when the NX huge page mitigation is enabled (mindblowing) and trigger the WARN that fires on reserved SPTE bits being set. KVM has required NX support for SVM since commit b26a71a1a5b9 ("KVM: SVM: Refuse to load kvm_amd if NX support is not available") for exactly this reason, but apparently it never occurred to anyone to actually test NPT with the mitigation enabled. ------------[ cut here ]------------ spte = 0x800000018a600ee7, level = 2, rsvd bit

    netfilter: nf_tables: do not allow SET_ID to refer to another table

    In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: do not allow SET_ID to refer to another table When doing lookups for sets on the same batch by using its ID, a set from a different table can be used. Then, when the table is removed, a reference to the set may be kept after the set is freed, leading to a potential use-after-free. When looking for sets by ID, use the table that was used for the lookup by name, and only return sets belonging to that same table. This fixes CVE-2022-2586, also reported as ZDI-CAN-17470.

    virtio-gpu: fix a missing check to avoid NULL dereference

    In the Linux kernel, the following vulnerability has been resolved: virtio-gpu: fix a missing check to avoid NULL dereference 'cache_ent' could be set NULL inside virtio_gpu_cmd_get_capset() and it will lead to a NULL dereference by a lately use of it (i.e., ptr = cache_ent->caps_cache). Fix it with a NULL check. [ kraxel: minor codestyle fixup ]
