kernel: netfilter: conntrack: tcp: do not force CLOSE on invalid-seq RST without direction check

A flaw was found in the Linux kernel's netfilter conntrack TCP state machine. A remote attacker can exploit this vulnerability by sending a specially crafted sequence of TCP Transmission Control Protocol packets, specifically a SYN synchronize packet followed by an RST reset packet with an invali...

CVE-2026-58094 TOCTOU race in POSIX shared memory large page configuration

The FIOSSHMLPGCNF ioctl2 operation configures the page size for a largepage shared memory object. This is intended to be used immediately after creating the object, before any memory is allocated for the object. The handler checked whether a page size had already been configured without holding t...

The FIOSSHMLPGCNF ioctl2 operation configures the page size for a largepage shared memory object. This is intended to be used immediately after creating the object, before any memory is allocated for the object. The handler checked whether a page size had already been configured without holding t...

CVE-2026-58093

CVE-2026-58093 is a use-after-free vulnerability in the FreeBSD kernel tty subsystem , specifically in the TIOCSCTTY ioctl handler. The handler drops the tty lock to acquire the process tree lock but fails to revalidate the terminal's state upon reacquiring the tty lock, allowing it to link a con...

CVE-2026-58093 Kernel use-after-free via tty ioctls

The TIOCSCTTY ioctl handler drops the tty lock in order to acquire the process tree lock. After reacquiring the tty lock, the handler did not revalidate the state of the terminal, and could proceed to link a terminal that was concurrently being destroyed to the calling process' session. An...

EUVD-2026-66250

The TIOCSCTTY ioctl handler drops the tty lock in order to acquire the process tree lock. After reacquiring the tty lock, the handler did not revalidate the state of the terminal, and could proceed to link a terminal that was concurrently being destroyed to the calling process' session. An...

CVE-2026-58091 Kernel use-after-free via the SNDCTL_DSP_SYNCSTART ioctl

The implementation of this ioctl attempts to acquire locks on all channels in a sync group. If locking a channel would block, it releases the sync group list lock and sleeps. Upon reawakening, it is possible that the sync group structure is freed, but the implementation did not handle this...

CVE-2026-58091

CVE-2026-58091 is a kernel use-after-free in FreeBSD's sound(4) driver , triggered via the SNDCTL_DSP_SYNCSTART ioctl. When locking a channel in a sync group would block, the implementation releases the sync group list lock and sleeps; upon reawakening, the sync group structure may have been free...

kernel: netfilter: ipset: fix race between dump and ip_set_list resize

A flaw was found in the Linux kernel's netfilter ipset component. A race condition exists between the ipsetlist resize operation and dump operations. This can lead to a use-after-free vulnerability, where memory is accessed after it has been deallocated. A successful exploitation of this flaw cou...

kernel: netfilter: conntrack: tcp: do not force CLOSE on invalid-seq RST without direction check

A flaw was found in the Linux kernel's netfilter conntrack TCP state machine. A remote attacker can exploit this vulnerability by sending a specially crafted sequence of TCP Transmission Control Protocol packets, specifically a SYN synchronize packet followed by an RST reset packet with an invali...

kernel: scsi: target: iscsi: Validate CHAP_R length before base64 decode

A flaw was found in the Linux kernel's iSCSI target functionality. This vulnerability allows a remote attacker to cause a buffer overflow by sending a specially crafted Challenge-Handshake Authentication Authentication Protocol CHAP response. The system fails to validate the length of the...

kernel: sctp: purge outqueue on stale COOKIE-ECHO handling

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. This vulnerability, a use-after-free, occurs when the system processes a Stale Cookie ERROR during the setup or reconfiguration of an SCTP association. A remote attacker could exploit this by sending...

kernel: Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count

A flaw was found in the Linux kernel's synaptics-rmi4 input driver. The rmif3amapgpios function incorrectly allocates memory for the gpiokeymap, making it smaller than required. This allows a device reporting a specific gpiocount value to trigger an out-of-bounds read, leading to information...

kernel: i2c: stub: Reject I2C block transfers with invalid length

A flaw was found in the Linux kernel's i2c-stub driver. A local user with access to the /dev/i2c- device can exploit this vulnerability by issuing an I2C System Management Bus SMBus input/output control ioctl command with a specially crafted block transfer length. This invalid length can cause th...

kernel: Input: synaptics-rmi4 - bound the F30 keymap to the GPIO/LED count

A flaw was found in the Linux kernel's synaptics-rmi4 input driver. This vulnerability occurs because the driver incorrectly allocates memory for a keymap, leading to an out-of-bounds memory access. A local user with access to a specially crafted input device could exploit this to read or write t...

kernel: nvmet: fix pre-auth out-of-bounds heap read in Discovery Get Log Page

A flaw was found in the Linux kernel's nvmet subsystem. An unauthenticated remote attacker could exploit an out-of-bounds heap read vulnerability in the Discovery Get Log Page function. By sending a specially crafted request with a manipulated offset, an attacker could read sensitive kernel memor...

K000163099: Linux kernel vulnerability CVE-2026-53253

Security Advisory Description In the Linux kernel, the following vulnerability has been resolved: Bluetooth: bnep: reject short frames before parsing A BNEP peer can send a short BNEP SDU. bneprxframe reads the packet type byte immediately and, for control packets, reads the control opcode and...

SUSE CVE-2026-68470

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: validate extension-frame layout before RX Extension frames only have the extension header at the regular 802.11 header offset. The generic RX path can still reach helpers and interface dispatch code that read...

SUSE CVE-2026-72499

In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxtre: Free CQ toggle page after firmware teardown Free the toggle page only after firmware teardown completes so that an NQ interrupt arriving during bnxtqplibdestroycq won't write the toggle value to an already-freed page...
