Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: thermal/int340xthermal: handles datavault when the value is ZEROSIZEPTR. In some cases, GDDV returns a packet with a buffer of zero length. This causes kmemdup to return ZEROSIZEPTR 0x10. As a result, datavaultread encounters a...

In the Linux kernel, the following vulnerability has been resolved: drm: amd: display: Fix memory leakage This commit addresses the memory leakage issue in the dcconstructctx function...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the Linux kernel. A use-after-free occurred in the way the console subsystem utilized ioctls KDGKBSENT and KDSKBSENT. A local user could exploit this flaw to gain access to memory beyond its intended scope. The most significant threat posed by this vulnerability is to dat...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: media: pci: tw68: Fixed the nullptrderef bug in the buf prepare and finish steps. When the driver calls tw68riscbuffer to prepare the buffer, the function call dmaalloccoherent may fail, resulting in an empty buffer buf-cpu. Late...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.10, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: atm: atmtcp: Prevent arbitrary write in atmtcprecvcontrol. syzbot reported the issue below. 0 When atmtcpvopen or atmtcpvclose is called via connect or close, atmtcpsendcontrol is called to send a special message in the kernel. T...

Astra Linux – Vulnerability in Linux

A locking inconsistency issue was discovered in the tty subsystem of the Linux kernel through version 5.9.13. Files drivers/tty/ttyio.c and drivers/tty/ttyjobctrl.c may allow a read-after-free attack on TIOCGSID, also known as CID-c8bcd9c5be24...

Astra Linux – Vulnerability in Linux, Linux 5.10

In various setup methods of the USB gadget subsystem, there is a possibility of unauthorized writing due to an incorrect flag check. This could lead to a local escalation of privileges without the need for additional execution privileges. User interaction is not required for exploitation. Product...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: amdgpu/pm: prevented array underflow in vega20odneditdpmtable In the PPODEDITVDDCCURVE case, the “inputindex” variable is capped at 2, but its negative values are not checked, resulting in an out-of-bounds read. This value comes...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ASoC: ops: Rejecting out-of-bounds values in sndsocputvolsw We currently do not validate whether the values being set are within the range that we have advertised to userspace as valid. Instead, we reject any values that are out ...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: wcd-mbhc-v2: fixed resource leaks during component removal The MBHC resources must be released in case of component probe failures and removals; therefore, they cannot be tied to the lifetime of the component device...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the Linux kernel. A memory use-after-free vulnerability was identified in the perf subsystem, allowing a local attacker with permission to monitor perf events, thereby corrupting memory and potentially escalating privileges. The most significant threat of this vulnerabili...

kernel: Bluetooth: fix locking in hci_conn_request_evt() with HCI_PROTO_DEFER

A flaw was found in the Linux kernel's Bluetooth subsystem. Improper handling of locking within the hciconnrequestevt function, particularly when the HCIPROTODEFER protocol is active, can result in a Use-After-Free UAF vulnerability. This condition arises when a connection object is accessed afte...

kernel: wifi: nl80211: reject oversized EMA RNR lists

A flaw was found in the Linux kernel's nl80211 Wi-Fi subsystem. The nl80211parsernrelems function, responsible for parsing EMA RNR Enhanced Multiple Access Reduced Neighbor Report lists, does not properly handle an excessive number of nested NL80211ATTREMARNRELEMS inputs. This improper input...

kernel: net: qrtr: fix refcount saturation and potential UAF in qrtr_port_remove

A flaw was found in the Linux kernel's qrtr network subsystem. A race condition exists in the qrtrportremove function where the socket reference count is decremented prematurely. This allows a concurrent reader to access a socket whose reference count has dropped to zero, potentially leading to a...

kernel: Bluetooth: hci_sync: fix UAF in hci_le_create_cis_sync

A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a Use-After-Free UAF, allows an attacker to access memory after it has been freed. This can lead to a system crash, resulting in a Denial of Service DoS, or potentially enable an attacker to execute malicious code. Th...
