Astra Linux – Vulnerability in net-snmp

Net-SNMP is an SNMP application library, tools, and daemon. Prior to versions 5.9.5 and 5.10.pre2, a specially crafted packet sent to the net-SNMP snmptrapd daemon could cause a buffer overflow, resulting in the daemon crashing. This issue has been fixed in versions 5.9.5 and 5.10.pre2...

In the Linux kernel, the following vulnerability has been resolved: net/sched: schsfb: Replace the direct dequeue call with peek and qdiscdequeuepeeked. When sfb has children e.g., qfq qdisc whose peek callback is qdiscpeekdequeued, we could encounter a kernel panic. When the parent of such qdisc...

In the Linux kernel, the following vulnerability has been resolved: Net: Atlantic: RX pages that are consumed but not refilled from buffers. The aqringrxdeinit function only iterates over the range swhead, swtail, which is posted to the hardware. Since the page reuse strategy was introduced, a...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fixed the race condition in agent registration for HV VHCA stats The mlx5ehvvhcastatscreate function registers the stats agent through mlx5hvvhcaagentcreate. The helper function publishes the agent in hvvhca-agentstype...

In the Linux kernel, the following vulnerability has been resolved: In the net subsystem, within kcm: It is necessary to hold the RCU read lock while running the BPF parser. The function kcmparsefuncstrparser calls bpfprogrunpinoncpu, which prevents CPU migration. However, this call does not crea...

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

In the Linux kernel, the following vulnerabilities have been resolved: - net: slip: Serialize the receive process during buffer reallocation. slreallocbufs replaces rbuff and updates the buffer size while holding sl-lock. slreceivebuf reads these fields and writes data through rbuff without holdi...

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

In the Linux kernel, the following vulnerability has been resolved: net: psample: Fixed an information leak in PSAMPLEATTRDATA. The psample open code uses nlaput to presumably avoid wiping the data with zeros, and instead overwrites it with packet data. This open coding does not clear the padding...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: virtio-net: Ensure that TCP packets do not overflow the gsosegs field. The user can specify any value less than TCPMINGSOSIZE = 8 for the gsosize parameter in a packet sent using a AFPACKETPACKETVNETHDR socket. At the same time,...

In the Linux kernel, the following vulnerability has been resolved: Wifi: ath9k: hifusb: Do not dereference hifdev after re-arming the firmware request The ath9khifrequestfirmware function re-arms an asynchronous firmware load via requestfirmwarenowait, passing hifdev as the completion context...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/sched: rejecting overly deep qdisc hierarchies. Deep qdisc hierarchies can lead to excessive recursion in the qdisc tree walkers, potentially exhausting the kernel stack. The existing loop checks do not cover the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: In net/sched, there’s an issue where hhfchange function clamps the value of q-quantum before execution, to avoid overflow. The hhfinit function sets q-quantum to pschedmtuqdiscdevsch, without any checks for overflow. A device wit...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net: mana: Added NULL guards in the teardown process to prevent panics during attach failures. When queue allocation fails halfway through, error cleanup releases variables apc-txqp and apc-rxqs containing NULL values. Multipl...
