🚨 CVE-2026-64580
In the Linux kernel, the following vulnerability has been resolved:
xfrm6: clear dst.dev on error to avoid double netdev_put in xfrm6_fill_dst()
On the error path where in6_dev_get(dev) returns NULL, xfrm6_fill_dst()
releases the device reference with netdev_put() but leaves...
🚨 CVE-2026-64581
In the Linux kernel, the following vulnerability has been resolved:
xfrm: fix sk_dst_cache double-free in xfrm_user_policy()
xfrm_user_policy() clears the socket dst cache with __sk_dst_reset(),

🚨 CVE-2026-64582
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix a use-after-free problem in rxe_mmap
rxe_mmap() removes a rxe_mmap_info struct from the pending_mmaps list
and releases pending_lock while the struct's kref is still at 1...
🚨 CVE-2026-64586
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: drain bus_reset work on device removal
brcmf_fw_crashed() and the debugfs "reset" entry both schedule
drvr->bus_reset, whose callback recovers drvr through container_of()
and dereferences it...
🚨 CVE-2026-64597
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix double-free in SMB2_close() replay
A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_close_init() fails before the next send, cleanup
retains the...
🚨 CVE-2026-64598
In the Linux kernel, the following vulnerability has been resolved:
smb/client: Fix error code in smb2_aead_req_alloc()
The "*num_sgs" variable is a u32 so "ERR_PTR(*num_sgs)" doesn't work.
We would have to do something similar to the previous line where it's
cast to int and...
🚨 CVE-2026-64599
In the Linux kernel, the following vulnerability has been resolved:
crypto: amlogic - avoid double cleanup in meson_crypto_probe()

reads...
🚨 CVE-2026-68085
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_uart: clear HCI_UART_SENDING when write_work is canceled

queueing it again. Currently this bit is not cleared when...
🚨 CVE-2026-68091
In the Linux kernel, the following vulnerability has been resolved:
HID: wacom: stop hardware after post-start probe failures
wacom_parse_and_register() starts HID hardware before registering inputs
and initializing pad LEDs/remotes. Those later steps can fail, but their
error...
🚨 CVE-2026-68098
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: bound DACL dedup walk to copied ACEs
set_ntacl_dacl() can stop copying ACEs before consuming the full input
DACL when size accounting overflows.
When that happens, num_aces reflects only the ACEs that...
🚨 CVE-2026-68100
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate num_subauth when copying ACE in set_ntacl_dacl
set_ntacl_dacl() copies each ACE from the attacker-controlled stored
security descriptor verbatim into the response DACL without checking...
🚨 CVE-2026-68103
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: reject mapping a reserved doorbell to a new queue
