kernel: io_uring IORING_OP_SOCKET double free

The Linux kernel io_uring IORING_OP_SOCKET operation contained a double free in function __sys_socket_file() in file net/socket.c. This issue was introduced in da214a475f8bd1d3e9e7a19ddfeb4d1617551bab and fixed in 649c15c7691e9b13cbe9bf6c65c365350e056067.

Copy_from_user Spectre-V1 Gadget in Linux Kernel

Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec allowing a user to bypass the "access_ok" check and pass a kernel pointer to copy_from_user(). This would allow an attacker to leak information. We recommend upgrading beyond commit 74e19ef0ff8061ef55957c3abd71614ef0f42f47

Use after free in io_uring in the Linux Kernel

There is a logic error in io_uring's implementation which can be used to trigger a use-after-free vulnerability leading to privilege escalation. In the io_prep_async_work function the assumption that the last io_grab_identity call cannot return false is not true, and in this case the function will use the init_cred or the previous linked requests identity to do operations instead of using the current identity. This can lead to reference counting issues causing use-after-free. We recommend upgrading past version 5.10.161.

Possibility of deadlock in libbpf function sock_hash_delete_elem

A deadlock flaw was found in the Linux kernel’s BPF subsystem. This flaw allows a local user to potentially crash the system.

EL Injection Vulnerability in Hitachi Replication Manager

Expression Language Injection vulnerability in Hitachi Replication Manager on Windows, Linux, Solaris allows Code Injection.This issue affects Hitachi Replication Manager: before 8.8.5-02.

kernel: event code falling outside of a bitmap in input_set_capability() leads to panic

An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause a denial of service (panic) because input_set_capability mishandles the situation in which an event code falls outside of a bitmap.

kernel: ntfs3 subsystem does not properly check for correctness during disk reads

An issue was discovered in the Linux kernel before 6.2. The ntfs3 subsystem does not properly check for correctness during disk reads, leading to an out-of-bounds read in ntfs_set_ea in fs/ntfs3/xattr.c.

A vulnerability was reported in ThinkPad T14s Gen 3 and X13 Gen3 that could cause the BIOS tamper detection mechanism to not trigger under specific circumstances which could allow unauthorized access.

kernel: use-after-free due to race condition occurring in dvb_ca_en50221.c

An issue was discovered in the Linux kernel through 6.0.10. In drivers/media/dvb-core/dvb_ca_en50221.c, a use-after-free can occur is there is a disconnect after an open, because of the lack of a wait_event.

kernel: use-after-free due to race condition occurring in dvb_net.c

An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a .disconnect versus dvb_device_open race condition that leads to a use-after-free.

kernel: use-after-free due to race condition occurring in dvb_register_device()

An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvbdev.c has a use-after-free, related to dvb_register_device dynamically allocating fops.

Kernel: A use-after-free due to race between scr24x_open() and scr24x_remove()

An issue was discovered in the Linux kernel through 6.0.6. drivers/char/pcmcia/scr24x_cs.c has a race condition and resultant use-after-free if a physically proximate attacker removes a PCMCIA device while calling open(), aka a race condition between scr24x_open() and scr24x_remove().

Kernel: A race condition between cm4040_open() and reader_detach() may result in UAF

An issue was discovered in the Linux kernel through 6.0.6. drivers/char/pcmcia/cm4040_cs.c has a race condition and resultant use-after-free if a physically proximate attacker removes a PCMCIA device while calling open(), aka a race condition between cm4040_open() and reader_detach().

Kernel: Race between cmm_open() and cm4000_detach() result in UAF

An issue was discovered in the Linux kernel through 6.0.6. drivers/char/pcmcia/cm4000_cs.c has a race condition and resultant use-after-free if a physically proximate attacker removes a PCMCIA device while calling open(), aka a race condition between cmm_open() and cm4000_detach().
