A issue was discovered in net/netfilter/nftablesapi.c within the Linux kernel prior to version 5.19.6. A denial of service can occur when binding to an already bound chain...

Astra Linux – Vulnerability in Linux 5.15

A issue was discovered in ksmbd within the Linux kernel versions 5.15 through 5.19, prior to 5.19.2. The file fs/ksmbd/smb2pdu.c omits a kfree call in certain error conditions during the smb2handlenegotiate process, resulting in a memory leak...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

An integer overflow or wrap-around vulnerability exists in the OpenEuler kernel on Linux file system modules, allowing for forced integer overflow. This issue affects the OpenEuler kernel, starting from version 4.19.90, up to and including version 4.19.90-2401.3, as well as versions 5.10.0-60.18....

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A out-of-bounds memory read flaw was discovered in the Linux kernel’s BPF subsystem, related to how a user calls the bpftailcall function with a key that is larger than the maxentries of the map. This flaw allows a local user to gain unauthorized access to data...

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

A use-after-free vulnerability exists in the Linux kernel’s net/sched: schhfsc HFSC qdisc traffic control component, which can be exploited to achieve local privilege escalation. If a class with a link-sharing curve i.e., with the HFSCFSC flag set has a parent without a link-sharing curve, then...

Astra Linux – Vulnerability in Linux 5.10

A NULL pointer dereference flaw was discovered in the Linux kernel’s X.25 set of standardized network protocol functions. This flaw allows a local user to crash the system by terminating their session using a simulated Ethernet card while continuing to use that connection...

Astra Linux – Vulnerability in Linux 5.15

A buffer overflow vulnerability was discovered in the Linux kernel’s Intel iSMT SMBus host controller driver. This vulnerability allows a local user to crash the system by triggering the I2CSMBUSBLOCKDATA function with malicious input data. source-iocs-preserved const=I2CSMBUS...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

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

A out-of-bounds read vulnerability was discovered in smbCalcSize in the fs/smb/client/netmisc.c file within the Linux kernel. This issue could allow a local attacker to crash the system or leak internal kernel information...

Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in vDPA with the VDUSE backend. Currently, there are no checks in the VDUSE kernel driver to ensure that the size of the device configuration space is consistent with the features advertised by the VDUSE user-space application. In the event of a mismatch, the Virtio driver...

Astra Linux – Vulnerability in Linux 5.10

Ubuntu Linux 6.8 GA retains the legacy AFUNIX garbage collector, but the upstream commit 8594d9b85c07 "afunix: Do not call skbget for OOB skb" addresses this issue. When orphaned MSGOOB sockets reach unixgc, the garbage collector still calls kfreeskb, assuming that OOB SKBs hold two references...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

A denial-of-service vulnerability due to a deadlock was discovered in sctpautoasconfinit in the net/sctp/socket.c file within the SCTP subsystem of the Linux kernel. This flaw allows users with local user privileges to trigger a deadlock and potentially cause the system to crash...

Astra Linux – Vulnerability in Linux

A use-after-free occurred in the function hcisockboundioctl of the Linux kernel’s HCI subsystem. This issue arises when the user calls ioct HCIUNBLOCKADDR, or when the call to hciunregisterdev triggers a race condition, along with the calls hcisockblacklistadd, hcisockblacklistdel, hcigetconninfo...

Astra Linux – Vulnerability in Linux 5.10, Linux

Several Linux PV device frontends are vulnerable to attacks by backends that use grant table interfaces to remove access rights from resources. This can lead to potential data leaks, data corruption by malicious backends, and denial of service attacks. The backends that use these interfaces may n...

Astra Linux – Vulnerability in Linux

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

Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw was discovered in the Linux kernel. Measuring the usage of shared memory does not scale well with large counts of shared memory segments, which could lead to resource exhaustion and Denial-of-Service attacks...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/amdgpu: fixed the gart.bo pincount leak. gmcv9,100gartdisable is not called when there’s no corresponding gartenable function in the SRIOV case. This will lead to a gart.bo pincount leak when the driver is unloaded...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: usb:typec:tipd: The WARNON message in tps6598xblockread has been removed. Calling tps6598xblockread with a parameter length that exceeds the allowed limit can be handled by simply returning an error. There is no need to cause...
