CVE-2022-1974
A use-after-free flaw was found in the Linux kernel's NFC core functionality due to a race condition between kobject creation and delete. This vulnerability allows a local attacker with CAP_NET_ADMIN privilege to leak kernel information.
- Actualiza a 5.4.0-1070.80
Publicación ActualizaciónCVE-2022-3028
A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket.

Publicación ActualizaciónCVE-2022-2153
A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service.

Publicación ActualizaciónCVE-2022-1204
A use-after-free flaw was found in the Linux kernel’s Amateur Radio AX.25 protocol functionality in the way a user connects with the protocol. This flaw allows a local user to crash the system.
- Actualiza a 5.4.0-1066.76
Publicación ActualizaciónCVE-2022-1198
A use-after-free vulnerabilitity was discovered in drivers/net/hamradio/6pack.c of linux that allows an attacker to crash linux kernel by simulating ax25 device using 6pack driver from user space.
- Actualiza a 5.4.0-1065.75
Publicación ActualizaciónCVE-2022-1016
A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker.
- Actualiza a 5.4.0-1060.68
Publicación ActualizaciónCVE-2022-0850
A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to userspace.
- Actualiza a 5.4.0-1043.47
Publicación ActualizaciónCVE-2022-0812
An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.
- Actualiza a 5.4.0-1016.17
Publicación ActualizaciónCVE-2022-1199
A flaw was found in the Linux kernel. This flaw allows an attacker to crash the Linux kernel by simulating amateur radio from the user space, resulting in a null-ptr-deref vulnerability and a use-after-free vulnerability.
- Actualiza a 5.4.0-1066.76
Publicación ActualizaciónCVE-2022-1184
A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel’s filesystem sub-component. This flaw allows a local attacker with a user privilege to cause a denial of service.
- Actualiza a 5.4.0-1091.102
Publicación ActualizaciónCVE-2022-0168
A denial of service (DOS) issue was found in the Linux kernel’s smb2_ioctl_query_info function in the fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system.
- Actualiza a 5.4.0-1091.102
Publicación ActualizaciónCVE-2021-3669
A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS.
- Actualiza a 5.4.0-1082.93
Publicación ActualizaciónCVE-2022-2991
A heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged code on the target system to exploit this vulnerability.
- Actualiza a 5.4.0-1066.76
Publicación ActualizaciónCVE-2021-4159
A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel.
- Actualiza a 5.4.0-1071.81
Publicación ActualizaciónCVE-2021-4155
A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS filesystem otherwise not accessible to them.
- Actualiza a 5.4.0-1053.60
Publicación ActualizaciónCVE-2022-2978
A flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function security_inode_alloc to fail with following call to function nilfs_mdt_destroy. A local user could use this flaw to crash the system or potentially escalate their privileges on the system.
- Actualiza a 5.4.0-1074.85
Publicación ActualizaciónKernel: security regression for cve-2018-13405
A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. This vulnerability is similar to the previous CVE-2018-13405 and adds the missed fix for the XFS.
