kernel: ext4: don't set up encryption key during jbd2 transaction

A flaw exists in the ext4 filesystem implementation in the Linux kernel such that the function ext4unlink extended a journaling transaction too far so that it included a call to ext4findentry. However, ext4findentry may need to set up a directory’s encryption key — which can cause a deadlock when...

A vulnerability was found in the Linux Kernel in the l2capconndel in net/bluetooth/l2capcore.c function in the Bluetooth component. This issue leads to a use-after-free problem...

kernel: use-after-free after failed devlink reload in devlink_param_get

A flaw was found in the Netlink device interface implementation in the Linux kernel that improperly handled certain error conditions, leading to a use-after-free issue with some network device drivers. A local attacker with admin access to the network device could use this to cause a denial of...

kernel: l2tp: missing lock when clearing sk_user_data can lead to NULL pointer dereference

A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol L2TP. A missing lock when clearing skuserdata can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service...

UBUNTU-CVE-2023-28327

A NULL pointer dereference flaw was found in the UNIX protocol in net/unix/diag.c In unixdiaggetexact in the Linux Kernel. The newly allocated skb does not have sk, leading to a NULL pointer. This flaw allows a local user to crash or potentially cause a denial of service...

CVE-2023-2008

A flaw was found in the Linux kernel's udmabuf device driver. The specific flaw exists within a fault handler. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an array. An attacker can leverage this vulnerability to...

kernel: FUSE filesystem low-privileged user privileges escalation

A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalat...

ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF

A use-after-free flaw was found in sndctlelemread in sound/core/control.c in Advanced Linux Sound Architecture ALSA subsystem in the Linux kernel. In this flaw a normal privileged, local attacker may impact the system due to a locking issue in the compat path, leading to a kernel information leak...

kernel: use-after-free caused by l2cap_reassemble_sdu() in net/bluetooth/l2cap_core.c

A use-after-free flaw was found in the Linux kernel’s L2CAP bluetooth functionality in how a user triggers a race condition by two malicious flows in the L2CAP bluetooth packets. This flaw allows a local or bluetooth connection user to crash the system or potentially escalate privileges...

kernel: FUSE filesystem low-privileged user privileges escalation

A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalat...

DEBIAN-CVE-2023-0210

A bug affects the Linux kernel’s ksmbd NTLMv2 authentication and is known to crash the OS immediately in Linux-based systems...

CVE-2023-1075

A flaw was found in the Linux Kernel. The tlsistxready incorrectly checks for list emptiness, potentially accessing a type confused entry to the listhead, leaking the last byte of the confused field that overlaps with rec-txready...

CVE-2023-1079

A flaw was found in the Linux kernel. A use-after-free may be triggered in asuskbdbacklightset when plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to the previous known CVE-2023-25012, but in asus devices, the workstruct may be scheduled by...

CVE-2021-3923

A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdmacm device node. While this access is unlikely to leak sensitive user information, it can be...

CVE-2022-3637

A flaw was found in the Linux Kernel, affecting the jlinkinit function of the monitor/jlink.c file in the BlueZ component. Manipulation leads to a denial of service...

CVE-2023-1078

A flaw was found in the Linux Kernel in RDS Reliable Datagram Sockets protocol. The rdsrmzerocopycallback uses listentry on the head of a list causing a type confusion.
