Debian Linux vulnerabilities

CVE-2017-5669 [HIGH] CVE-2017-5669: The do_shmat function in ipc/shm.c in the Linux kernel through 4.9.12 does not restrict the address The do_shmat function in ipc/shm.c in the Linux kernel through 4.9.12 does not restrict the address calculated by a certain rounding operation, which allows local users to map page zero, and consequently bypass a protection mechanism that exists for the mmap system call, by making crafted shmget and shmat system calls in a privileged context.

CVE-2021-26720 [HIGH] CWE-59 CVE-2021-26720: avahi-daemon-check-dns.sh in the Debian avahi package through 0.8-4 is executed as root via /etc/net avahi-daemon-check-dns.sh in the Debian avahi package through 0.8-4 is executed as root via /etc/network/if-up.d/avahi-daemon, and allows a local attacker to cause a denial of service or create arbitrary empty files via a symlink attack on files under /run/avahi-daemon. NOTE: this only affects the packaging for Debian GNU/Linux (used indirectly by SUSE

CVE-2021-23177 [HIGH] CWE-59 CVE-2021-23177: An improper link resolution flaw while extracting an archive can lead to changing the access control An improper link resolution flaw while extracting an archive can lead to changing the access control list (ACL) of the target of the link. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to change the ACL of a file on the system and gain mor

CVE-2018-16837 [HIGH] CWE-214 CVE-2018-16837: Ansible "User" module leaks any data which is passed on as a parameter to ssh-keygen. This could lea Ansible "User" module leaks any data which is passed on as a parameter to ssh-keygen. This could lean in undesirable situations such as passphrases credentials passed as a parameter for the ssh-keygen executable. Showing those credentials in clear text form for every user which have access just to the process list.

CVE-2020-6574 [HIGH] CVE-2020-6574: Insufficient policy enforcement in installer in Google Chrome on OS X prior to 85.0.4183.102 allowed Insufficient policy enforcement in installer in Google Chrome on OS X prior to 85.0.4183.102 allowed a local attacker to potentially achieve privilege escalation via a crafted binary.

CVE-2021-27379 [HIGH] CVE-2021-27379: An issue was discovered in Xen through 4.11.x, allowing x86 Intel HVM guest OS users to achieve unin An issue was discovered in Xen through 4.11.x, allowing x86 Intel HVM guest OS users to achieve unintended read/write DMA access, and possibly cause a denial of service (host OS crash) or gain privileges. This occurs because a backport missed a flush, and thus IOMMU updates were not always correct. NOTE: this issue exists because of an incomplete fix for CVE-

CVE-2022-3625 [HIGH] CWE-119 CVE-2022-3625: A vulnerability was found in Linux Kernel. It has been classified as critical. This affects the func A vulnerability was found in Linux Kernel. It has been classified as critical. This affects the function devlink_param_set/devlink_param_get of the file net/core/devlink.c of the component IPsec. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier VDB-211929 was assigned to this vulnerability.

CVE-2021-1076 [HIGH] CVE-2021-1076: NVIDIA GPU Display Driver for Windows and Linux, all versions, contains a vulnerability in the kerne NVIDIA GPU Display Driver for Windows and Linux, all versions, contains a vulnerability in the kernel mode layer (nvlddmkm.sys or nvidia.ko) where improper access control may lead to denial of service, information disclosure, or data corruption.

CVE-2024-58240 [HIGH] CWE-416 CVE-2024-58240: In the Linux kernel, the following vulnerability has been resolved: tls: separate no-async decrypti In the Linux kernel, the following vulnerability has been resolved: tls: separate no-async decryption request handling from async If we're not doing async, the handling is much simpler. There's no reference counting, we just need to wait for the completion to wake us up and return its result. We should preferably also use a separate crypto_wait. I'm

CVE-2025-37839 [HIGH] CVE-2025-37839: In the Linux kernel, the following vulnerability has been resolved: jbd2: remove wrong sb->s_sequen In the Linux kernel, the following vulnerability has been resolved: jbd2: remove wrong sb->s_sequence check Journal emptiness is not determined by sb->s_sequence == 0 but rather by sb->s_start == 0 (which is set a few lines above). Furthermore 0 is a valid transaction ID so the check can spuriously trigger. Remove the invalid WARN_ON.

CVE-2025-39880 [HIGH] CWE-704 CVE-2025-39880: In the Linux kernel, the following vulnerability has been resolved: libceph: fix invalid accesses t In the Linux kernel, the following vulnerability has been resolved: libceph: fix invalid accesses to ceph_connection_v1_info There is a place where generic code in messenger.c is reading and another place where it is writing to con->v1 union member without checking that the union member is active (i.e. msgr1 is in use). On 64-bit systems, con->v1.au

CVE-2018-6764 [HIGH] CWE-346 CVE-2018-6764: util/virlog.c in libvirt does not properly determine the hostname on LXC container startup, which al util/virlog.c in libvirt does not properly determine the hostname on LXC container startup, which allows local guest OS users to bypass an intended container protection mechanism and execute arbitrary commands via a crafted NSS module.

CVE-2017-7889 [HIGH] CWE-732 CVE-2017-7889: The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/cha

CVE-2024-49882 [HIGH] CWE-415 CVE-2024-49882: In the Linux kernel, the following vulnerability has been resolved: ext4: fix double brelse() the b In the Linux kernel, the following vulnerability has been resolved: ext4: fix double brelse() the buffer of the extents path In ext4_ext_try_to_merge_up(), set path[1].p_bh to NULL after it has been released, otherwise it may be released twice. An example of what triggers this is as follows: split2 map split1 |--------|-------|--------| ext4_ext_ma

We should guarantee the timer is no longer active before kfree(sbi). When filesys

CVE-2020-11739 [HIGH] CWE-362 CVE-2020-11739: An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service or possibly gain privileges because of missing memory barriers in read-write unlock paths. The read-write unlock paths don't contain a memory barrier. On Arm, this means a processor is allowed to re-order the memory access with the preceding ones. In oth

CVE-2022-34670 [HIGH] CWE-197 CVE-2022-34670: NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer handler, where NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer handler, where an unprivileged regular user can cause truncation errors when casting a primitive to a primitive of smaller size causes data to be lost in the conversion, which may lead to denial of service or information disclosure.
