kernel: concurrency use-after-free between drm_setmaster_ioctl and drm_mode_getresources

A use-after-free vulnerability was found in drm_lease_held in drivers/gpu/drm/drm_lease.c in the Linux kernel due to a race problem. This flaw allows a local user privilege attacker to cause a denial of service (DoS) or a kernel information leak.

kernel: KVM: NULL pointer dereference in kvm_dirty_ring_push in virt/kvm/dirty_ring.c

A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service.

kernel: A race condition bug in rose_connect()

An issue found in linux-kernel that leads to a race condition in rose_connect(). The rose driver uses rose_neigh->use to represent how many objects are using the rose_neigh. When a user wants to delete a rose_route via rose_ioctl(), the rose driver calls rose_del_node() and removes neighbours only if their “count” and “use” are zero.

kernel: Null pointer dereference and use after free in net/ax25/ax25_timer.c

A NULL pointer dereference flaw was found in the Linux kernel’s Amateur Radio AX.25 protocol functionality in the way a user connects with the protocol. This flaw allows a local user to crash the system.

kernel: Use after free in net/ax25/af_ax25.c

A use-after-free flaw was found in the Linux kernel’s Amateur Radio AX.25 protocol functionality in the way a user connects with the protocol. This flaw allows a local user to crash the system.

kernel: use-after-free in drivers/net/hamradio/6pack.c

A use-after-free vulnerabilitity was discovered in drivers/net/hamradio/6pack.c of linux that allows an attacker to crash linux kernel by simulating ax25 device using 6pack driver from user space.

kernel: A possible race condition (use-after-free) in drivers/net/hamradio/6pack ( mkiss.c) after unregister_netdev

A use-after-free vulnerability was found in the Linux kernel in drivers/net/hamradio. This flaw allows a local attacker with a user privilege to cause a denial of service (DOS) when the mkiss or sixpack device is detached and reclaim resources early.

kernel: KVM: cmpxchg_gpte can write to pfns outside the userspace region

A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and potentially corrupt the kernel, resulting in a denial of service condition.

kernel: race condition in snd_pcm_hw_free leading to use-after-free

A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system.

kernel: Linux Kernel io_uring Use-After-Free Privilege Escalation Vulnerability

A flaw was found in the Linux kernel’s io_uring implementation. This flaw allows an attacker with a local account to corrupt system memory, crash the system or escalate privileges.

Okta Advanced Server Access Client for Linux and macOS prior to version 1.58.0 was found to be vulnerable to command injection via a specially crafted URL. An attacker, who has knowledge of a valid team name for the victim and also knows a valid target host where the user has access, can execute commands on the local system.

kernel: uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM

A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker.

kernel: an integer overflow in the vhost_vdpa_config_validate() can lead to out-of-bounds access on top of a 32-bit Linux kernel

An integer overflow flaw was found in the Linux kernel’s virtio device driver code in the way a user triggers the vhost_vdpa_config_validate function. This flaw allows a local user to crash or potentially escalate their privileges on the system.

Use after free in Extensions in Google Chrome prior to 99.0.4844.74 allowed an attacker who convinced a user to install a malicious extension to potentially exploit heap corruption via a crafted HTML page.

Use after free in Blink Layout in Google Chrome on Android prior to 99.0.4844.74 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption via a crafted HTML page.

kernel: swiotlb information leak with DMA_FROM_DEVICE

A memory leak flaw was found in the Linux kernel’s DMA subsystem, in the way a user calls DMA_FROM_DEVICE. This flaw allows a local user to read random memory from the kernel space.

kernel: information leak in copy_page_to_iter() in iov_iter.c

A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to userspace.

Inappropriate implementation in Autofill in Google Chrome prior to 99.0.4844.51 allowed a remote attacker to bypass navigation restrictions via a crafted HTML page.

Data leak in Canvas in Google Chrome prior to 99.0.4844.51 allowed a remote attacker who convinced a user to engage in screen sharing to potentially leak cross-origin data via a crafted HTML page.

Use after free in Browser Switcher in Google Chrome prior to 99.0.4844.51 allowed a remote attacker who convinced a user to engage in specific user interaction to potentially exploit heap corruption via user interaction.
