kernel: out-of-bounds read in libiscsi module

A flaw was found in the Linux kernel. An out-of-bounds read was discovered in the libiscsi module that could lead to reading kernel memory or a crash. The highest threat from this vulnerability is to data confidentiality as well as system availability...

kernel: iscsi: unrestricted access to sessions and handles

A flaw was found in the way access to sessions and handles was handled in the iSCSI driver in the Linux kernel. A local user could use this flaw to leak iSCSI transport handle kernel address or end arbitrary iSCSI connections on the system...

Double free

Shiftfs, an out-of-tree stacking file system included in Ubuntu Linux kernels, did not properly handle faults occurring during copyfromuser correctly. These could lead to either a double-free situation or memory not being freed at all. An attacker could use this to cause a denial of service kerne...

kernel: out-of-bounds read in libiscsi module

A flaw was found in the Linux kernel. An out-of-bounds read was discovered in the libiscsi module that could lead to reading kernel memory or a crash. The highest threat from this vulnerability is to data confidentiality as well as system availability...

kernel: heap buffer overflow in the iSCSI subsystem

A flaw was found in the Linux kernel. A heap buffer overflow in the iSCSI subsystem is triggered by setting an iSCSI string attribute to a value larger than one page and then trying to read it. The highest threat from this vulnerability is to data confidentiality and integrity as well as system...

kernel: use-after-free in i915_ppgtt_close in drivers/gpu/drm/i915/i915_gem_gtt.c

A use-after-free flaw was found in the Linux kernel’s GPU driver functionality when destroying GEM context. A local user could use this flaw to crash the system or potentially escalate their privileges...

kernel: increase slab leak leads to DoS

A flaw was found in the way memory resources were freed in the unixstreamrecvmsg function in the Linux kernel when a signal was pending. This flaw allows an unprivileged local user to crash the system by exhausting available memory. The highest threat from this vulnerability is to system...

kernel: SCSI target (LIO) write to any block on ILO backstore

A flaw was found in the Linux kernel’s implementation of the Linux SCSI target host, where an authenticated attacker could write to any block on the exported SCSI device backing store. This flaw allows an authenticated attacker to send LIO block requests to the Linux system to overwrite data on t...

A flaw was found in the Linux kernel’s implementation of the Linux SCSI target host, where an authenticated attacker could write to any block on the exported SCSI device backing store. This flaw allows an authenticated attacker to send LIO block requests to the Linux system to overwrite data on t...

USN-4879-1 linux, linux-aws, linux-azure, linux-gcp, linux-hwe-5.8, linux-kvm, linux-oracle, linux-raspi vulnerabilities

It was discovered that the Marvell WiFi-Ex device driver in the Linux kernel did not properly validate ad-hoc SSIDs. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2020-36158 Loris Reiff discovered that the BPF implementation in t...

UBUNTU-CVE-2021-28375

An issue was discovered in the Linux kernel through 5.11.6. fastrpcinternalinvoke in drivers/misc/fastrpc.c does not prevent user applications from sending kernel RPC messages, aka CID-20c40794eb85. This is a related issue to CVE-2019-2308...

kernel: bad kfree in auditfilter.c may lead to escalation of privilege

A flaw was found in the Linux kernel. A logic error in auditdatatoentry can lead to a local escalation of privilege without user interaction needed. A local attacker with special user privilege could crash the system leading to information leak. The highest threat from this vulnerability is to da...

UBUNTU-CVE-2021-26932

An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one is reported to the backend driver, and the backend driver then...

kernel: ICMP rate limiting can be used for DNS poisoning attack

A flaw in the way reply ICMP packets are limited in the Linux kernel functionality was found that allows to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypassing source port UDP randomization. The highest threat from this vulnerability is to confidentialit...

kernel: Nfsd failure to clear umask after processing an open or create

A flaw incorrect umask during file or directory modification in the Linux kernel NFS network file system functionality was found in the way user create and delete object using NFSv4.2 or newer if both simultaneously accessing the NFS by the other process that is not using new NFSv4.2. A user with...
