In the Linux kernel, the following vulnerabilities have been resolved: usb: idmouse: Fixed an issue where an uninitialized value was present in idmouseopen. In idmousecreateimage, if any ftipcommand fails, it will proceed to the reset label. However, this results in the data in...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: mmc: wmt-sdmmc: fixed the return value check in mmcaddhost The mmcaddhost function may return an error. If we ignore its return value, the memory allocated in mmcallochost will be leaked, leading to a kernel crash due to the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sched/scs: The task stack state is reset in bringupcpu. When a CPU is hot-plugged, the idle task on that CPU calls several layers of C code before finally leaving the kernel. When KASAN is in use, a “poisoned” shadow is left behi...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: i2c: piix4: Fixed a memory leak in the EFCH MMIO support. The recently added support for EFCH MMIO regions introduced a memory leak in that code path. The leak occurs because releaseresource simply removes the resource from the...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Drivers: Serial: JSM – fixed some leaks in the probe. This error path needs to be unwound instead of just being returned directly...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: nftflowoffload: Release dst if direct xmit path is used Direct xmit does not use it because it calls devqueuexmit to send packets; therefore, it calls dstrelease. kmemleak reports: Unreferenced object...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: iouring: fixed the memory leak related to the uid during file registration. When there are no files for iosqefilesscm to process within a certain range, it will free all resources and return. However, it forgot to set the uid...

Astra Linux – Vulnerability in Linux

In the drivers/target/targetcorexcopy.c file within the Linux kernel, prior to version 5.10.7, insufficient identifier checking in the LIO SCSI target code could be exploited by remote attackers to read or write files through directory traversal in an XCOPY request, known as CID-2896c93811e3. For...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: i2c: mux: In the function reg, it is necessary to check the return value after calling platformgetresource. This could lead to a null-ptr-deref issue in resourcesize if platformgetresource returns NULL. It is recommended to call...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ipv6/sit: Use DEVSTATSINC to avoid data races. syzbot/KCSAN reported that multiple CPUs are updating dev-stats.txerror concurrently. This occurs because sit tunnels use NETIFFLLTX, which means their ndostartxmit function is not...
