Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

A vulnerability was discovered in vhostnewmsg in drivers/vhost/vhost.c within the Linux kernel. This issue arises due to the improper initialization of memory in messages transmitted between virtual guests and the host operating system, as implemented in the vhostnewmsg function. This vulnerabili...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/amdgpu: fixed out-of-bounds access to the mmhub client ID. Properly handled cid 0x140...

Astra Linux – Vulnerability in Linux 5.15

A use-after-free flaw was discovered in lan78xxdisconnect in drivers/net/usb/lan78xx.c within the network sub-component, net/usb/lan78xx, in the Linux kernel. This flaw allows a local attacker to cause the system to crash when the LAN78XX USB device is disconnected...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Do not overwrite the KMS surface dirty tracker. We were overwriting the surface’s dirty tracker, which caused a memory leak...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Watchdog: sp5100tco – Fixed a memory leak related to the EFCH MMIO resource. Unlike releasememregion, a call to releaseresource does not free the resource automatically; therefore, it must be freed explicitly to avoid a memory...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel versions 5.8 through 5.19.x, prior to 5.19.16, local attackers who were able to inject WLAN frames into the mac80211 stack could carry out a NULL pointer dereferencing denial-of-service attack against the beacon protection of P2P devices...

Astra Linux – Vulnerability in Linux 5.10, Linux

In nftablesupdtable, if nftablestableenable returns an error, nfttransdestroy is called to free the transaction object. nfttransDestroy calls listdel, but the transaction was never placed on a list—the list head contains only zeros, which results in a NULL pointer being dereferenced...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/ast: astdp: Fixed the timeout for enabling the video signal The ASTDP transmitter sometimes takes up to 1 second to enable the video signal, while the timeout is only 200 msec. This results in a kernel error message. The...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iouring: prevents reg-wait speculation. By using ENTEREXTARGREG instead of passing a user pointer along with arguments for the waiting loop, the user can specify an offset within a pre-mapped region of memory. In this case, offse...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mm/shmem: Disable the PMD-sized page cache if necessary. For shmem files, it’s possible that a PMD-sized page cache cannot be supported by xarray. For example, a 512MB page cache on ARM64 when the base page size is 64KB cannot be...

In the Linux kernel, the following vulnerability has been resolved: IB/IPoIB: Fix legacy IPoIB due to wrong number of queues The cited commit creates child PKEY interfaces over netlink will multiple tx and rx queues, but some devices doesn't support more than 1 tx and 1 rx queues. This causes to ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/siw: Fixed a refcounting leak in siwcreateqp. The atomicinc function needs to be paired with an atomicdec function in the error handling path...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: can: dev: canrestart: fix use after free bug After calling netifrxniskb, dereferencing the skb is unsafe. In particular, the canframe field, which aliases skb memory, is accessed after the netifrxni function in the line:...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: Fixed the null pointer dereference issue. If SMU is disabled, during RAS initialization, there will be a null pointer dereference issue...

Rogue backends can cause Denial of Service DoS attacks on guests through high-frequency events. This CNA information record relates to multiple Common Vulnerabilities and Exposures CVEs; the text explains which aspects/vulnerabilities correspond to which CVEs. Xen allows for the execution of PV...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: octeontx2-af: fixed the double-free in rvunpcfreemem. Clang static checker scan-build warning: drivers/net/ethernet/marvell/octeontx2/af/rvunpc.c, line 2184, column 2: Attempt to free released memory. The function...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: kTLS; fixed a crash that occurred during the RX resync process. For the TLS RX resync process, we maintain a list of TLS contexts that require some attention. We communicate their resync information to the hardware...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iavf: Implement settime64 with -EOPNOTSUPP The ptpclocksettime function assumes that every ptpclock has implemented settime64. By using -EOPNOTSUPP as a stub, we prevent a NULL derefrence from occurring. This fix is similar to th...

Astra Linux – Vulnerability in Linux, Linux 5.10

Guests can trigger the reset/abort/crash of the NIC interface through netback. It is possible for a guest to trigger a NIC interface reset/abort/crash in a Linux-based network backend by sending certain types of packets. It seems to be an unstated assumption in the rest of the Linux network stack...
