In the Linux kernel, the following vulnerability has been resolved: drm/i915: Fixed the potential double-free of the bit17 bitmask. A userspace environment where multiple threads compete to set the tiling to I915TILINGNONE could lead to a double-free of the bit17 bitmask. Or, conversely, memory...

Astra Linux – Vulnerability in libstb

stbimage is a single-file library licensed under MIT that processes images. It might seem like stbiloadgifmain does not provide any guarantees regarding the content of the output value delays in case of failure. Although it sets delays to zero at the beginning, it does not do so if the image is n...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: blk-mq: Fixed the issue where blkmqtags double-freeed memory when nrrequests increased. In cases where user-triggered tags increase due to the nrrequests value in the queue sysfs attributes, hctx-schedtags will be directly freed...

Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in KVM AMD Secure Encrypted Virtualization SEV within the Linux kernel. A KVM guest that uses SEV-ES or SEV-SNP with multiple vCPUs can trigger a double fetch race condition vulnerability and invoke the VMGEXIT handler recursively. If an attacker manages to call the handler...

In the Linux kernel, the following vulnerabilities have been resolved: mptcp: fixed a double-free on the socket destructor function When an MPTCP server accepts an incoming connection, it clones its listener socket. However, the pointer to ‘inetopt’ for the new socket has the same value as the...

Astra Linux – Vulnerability in maven-shared-utils

In Apache Maven’s maven-shared-utils before version 3.3.3, the Commandline class could generate double-quoted strings without proper escaping, allowing for shell injection attacks...

A use-after-free vulnerability in the Linux kernel’s netfilter:nftables component can be exploited to achieve local privilege escalation. The nftverdictinit function allows positive values as drop errors within the hook verdict, and thus the nfhookslow function can cause a double-free vulnerabili...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fixed double-release of the compute pasid. If kfdprocessdeviceinitvm returns an error after the vm is converted to a compute vm and vm-pasid is set to compute pasid, KFD will not take the pdd-drmfile reference. As a...

Astra Linux – Vulnerability in Linux 5.10

iouring uses workFlags to determine which identities need to be retrieved from the calling process, ensuring that they are consistent with the calling process when executing IORINGOP. Some operations lack certain types, which can lead to incorrect reference counts, potentially causing a...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: scsi: fnic: Fixed a crash in fnicwqcmplhandler when FDMI times out. When both the RHBA and RPA FDMI requests time out, fnic reuses a frame to send ABTS for each of them. Upon completion of the sending process, this leads to a...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Fixed a double-free in the dma-buf feature. The error path through vfiopcicorefeaturedmabuf ignores its own advice to only use dmabufput after dmabufexport. Instead, it proceeds through the entire unwind chain. In the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: btrfs: fixed a situation where a double free of the qgroup record occurred after attempting to add a delayed ref head failed. In the previous code, it was possible for a double kfree scenario to occur when calling...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: IB/mlx5: Fixed error handling during the init stage to avoid double-freeing of the same QP and UAF. In the unlikely event that workqueue allocation fails and returns NULL in mlx5mkeycacheinit, delete the call to...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Firmware: armscmi: Fixed a double-free in the SMC transport cleanup process. When the generic SCMI code destroys a channel, it calls the chanfree callback function, which is defined by each transport. Since multiple protocols may...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ASoC: sma1307 – fixed the double-free of devmkzalloc memory. A previous change added NULL checks and cleanup procedures for allocation failures in sma1307settingloaded. However, the cleanup for modeset entries is incorrect. These...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: PCI: hv: Fixed double calls to idafree in the hvpciprobe error path. If hvpciprobe fails after storing the domain number in hbus-bridge-domainNr, a call to free this domainNr is made via pciBusReleaseEmulDomainNr. However, during...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fixed the issue where mr-map was freed twice.
