CVE Vulnerability Catalog

In the Linux kernel, the ksmbd module is vulnerable to a remotely triggerable NULL-dereference bug. The functions smb2_oplock_break_noti() and smb2_lease_break_noti() read the opinfo->conn pointer without READ_ONCE() or NULL check, allowing a concurrent SMB2 LOGOFF to set it to NULL and cause a kernel oops.

In the Linux kernel, a vulnerability was found in the synproxy mechanism due to missing synchronization when registering netfilter hooks on demand. When multiple users add the first iptables rules or nftables expressions concurrently, a race condition can occur in the reference counter. A mutex has been added to serialize access to the reference count control blocks from both frontends.

A vulnerability in the Linux kernel's 6LoWPAN multicast address compression function contains an off-by-one error. This overwrites the RIID field and leaks uninitialized kernel stack memory over the network.

In the Linux kernel, a vulnerability in the devlink mechanism causes a nested relation to not be released when a devlink instance fails before registration. This results in a memory leak of the devlink->rel structure.

A memory leak in the Linux kernel's Wi-Fi subsystem has been identified during 6 GHz scanning. The rdev->int_scan_req object is not freed when cfg80211_scan() fails because rdev->scan_req remains NULL, preventing proper memory release in ___cfg80211_scan_done().

In the Linux kernel, a vulnerability in the cfg80211 subsystem could cause a crash in mac80211 when eht_cap is set but eht_oper is missing. Consistency enforcement for HE/EHT elements has been added to prevent this.

A memory leak in the error path of hci_alloc_dev() in the Linux kernel was fixed. When Bluetooth HCI UART device initialization fails before registration, the HCI_UNREGISTER flag is not set, bypassing hci_release_dev() and leaking SRCU percpu memory. The fix explicitly calls cleanup_srcu_struct() in the unregistered branch of bt_host_release().

In the Linux kernel Bluetooth ISO subsystem, a reference leak of the hci_dev structure was found. The iso_conn_big_sync function fails to release the reference obtained by hci_get_route(), leading to memory exhaustion.

In the Linux kernel, the ability to set IP LSRR and SSRR options has been restricted to users with CAP_NET_RAW capability. This prevents unprivileged applications from forcing packet routing through attacker-controlled nodes to leak TCP ISN and other protocol information.

In the Linux kernel MRP subsystem, a vulnerability was found in the mrp_pdu_parse_vecattr() function. Parsing errors in vector attributes can lead to incorrect packet processing, including spurious events, skipped FirstValue fields, and incorrect attribute value incrementation.

A vulnerability in the Linux kernel uses an uninitialized stack variable in rseq_exit_user_update(). The issue stems from undefined initialization order in C structure fields, causing kernel information leak.

In the Linux kernel, the ALSA seq dummy driver has a vulnerability involving a stack overread when processing UMP events. Copying an event into a temporary structure smaller than struct snd_seq_ump_event causes out-of-bounds reads when delivering to subscribers.

A vulnerability was found in the Linux kernel's netlabel subsystem. The netlbl_unlabel_addrinfo_get() function did not validate the length of the mask attribute for unlabeled addresses, allowing a crafted Generic Netlink request with a valid IPv4/IPv6 address but a shorter mask. This caused incomplete data to be read as a full address structure, potentially leading to incorrect behavior or security issues.

A NULL pointer dereference vulnerability was found in the Linux kernel's GPIO driver for Marvell Armada. The suspend/resume functions are called for all GPIO banks, but only some support PWM. Accessing the mvpwm structure in a bank without PWM causes a kernel panic.

In the Linux kernel, a patch restricts the use of SO_ATTACH_FILTER (cBPF) on TCP sockets to users with CAP_NET_ADMIN capability. This prevents side-channel attacks where an unprivileged application could leak TCP sequence numbers.

In the Linux kernel, a vulnerability was found where it attempts to set up PHY-driven SFP cages when using the generic genphy driver. This leads to a deadlock on the RTNL lock because for genphy, PHY probing runs under RTNL, unlike other drivers.

In the Linux kernel, the Open vSwitch module has a vulnerability where kfree_skb can be called on an ERR_PTR pointer. This occurs when the reply buffer allocation happens after locking the mutex, and on failure the pointer is not cleared, leading to an attempt to free an invalid pointer.

In the Linux kernel GPIO driver for Rockchip, a memory leak of generic IRQ chip structures was found. These structures are not freed on driver removal, potentially leading to use-after-free and kernel crash.

In the Linux kernel, the ptp_ocp driver has a vulnerability due to incorrect resource freeing order. Pin resources are freed before ptp_clock_unregister() is called, leading to a use-after-free condition during driver removal.

In the Linux kernel, a vulnerability was found in netfilter where ebt_redirect_tg() dereferences br_port_get_rcu() return without NULL check, causing kernel panic when the bridge port is removed between hook invocation and NFQUEUE reinject. Userspace could also move the device to a different virtual interface, requiring packet drop.
