In the Linux kernel, the following vulnerability has been resolved: Wifi: ath9k: Delay all operations related to ath9kwmieventtasklet until initialization is complete. The ath9kwmieventtasklet function used in ath9khtc assumes that all data structures have been fully initialized by the time it...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: atm: nicstar: Fixed a possible use-after-free in nicstarcleanup The remove path of this module calls deltimer. However, that function does not wait until the timer handler finishes. This means that the timer handler may still be...

In the Linux kernel, the following vulnerabilities have been resolved: ipv6: Use RCU protection in ip6defaultadvmss. ip6defaultadvmss requires RCU protection to ensure that the network structure it reads does not disappear...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mptcp: fixed the “scheduling while atomic” issue in mptcppmnl.AppendNewLocalAddr. If multiple connection requests attempt to create an implicit mptcp endpoint simultaneously, more than one caller may end up using...

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: bpf: Ensuring that pending IRQ work is processed before freeing the ring buffer. A race condition was addressed in this fix, where irqwork could be queued in bpfringbufcommit, but the ring buffer was freed before the work execute...

In the Linux kernel, the following vulnerability has been resolved: media: netupunidvb: fix use-after-free at deltimer When the Universal DVB card is being detached, netupunidvbdmafini uses deltimer to stop the dma-timeout timer. However, when the timer handler netupunidvbdmatimeout is running,...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: i40e: A race condition was fixed by adding an intermediate filter synchronization state. A race condition in the i40e driver was addressed, preventing MAC/VLAN filters from becoming corrupted and leaking data. This issue occurs...

Astra Linux – Vulnerability in NTP

In NTP versions prior to 4.2.8p14 and 4.3.x before 4.3.100, ntpd allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address. This occurs because transmissions are rescheduled even when a packet lacks a valid origin timestamp...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Immediately reset the MMU context when the SMM flag is cleared The MMU context should be reset immediately when the SMM flag of the vCPU is cleared, so that the SMM flag in the MMU context is always synchronized with th...

Astra Linux – Vulnerability in NTP

In ntp 4.2.8p10, 4.2.8p11, 4.2.8p12, and 4.2.8p13, remote attackers can prevent a broadcast client from synchronizing its clock with a broadcast NTP server through soofed modes 3 and 5. The attacker must either be part of the same broadcast network or control a slave device in that broadcast...
