Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2016-20022)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the usb_parse_endpoint() function in drivers/usb/core/config.c when parsing the wMaxPacketSize field. A local user can perform a denial of service (DoS) attack.
Note, this vulnerability only affects products that are no longer supported by the supplier.
2) Improper Validation of Array Index (CVE-ID: CVE-2021-43389)
The vulnerability allows a local user to execute arbitrary code with elevated privileges.The vulnerability exists due to improper validation of array index in the ISDN CAPI implementation within detach_capi_ctr() function in drivers/isdn/capi/kcapi.c. A local user can send specially crafted data to the system and execute arbitrary code with elevated privileges.
3) Out-of-bounds read (CVE-ID: CVE-2021-4439)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to an out-of-bounds read error within the detach_capi_ctr() function in drivers/isdn/capi/kcapi.c. A local user can perform a denial of service (DoS) attack.
4) Out-of-bounds read (CVE-ID: CVE-2021-47219)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to an out-of-bounds read error within the resp_report_tgtpgs() function in drivers/scsi/scsi_debug.c. A local user can perform a denial of service (DoS) attack.
5) Use-after-free (CVE-ID: CVE-2021-47520)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the pch_can_rx_normal() function in drivers/net/can/pch_can.c. A local user can escalate privileges on the system.
6) Out-of-bounds read (CVE-ID: CVE-2021-47580)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to an out-of-bounds read error within the p_fill_from_dev_buffer(), resp_inquiry(), resp_requests(), resp_mode_sense(), resp_ie_l_pg(), resp_log_sense() and resp_report_zones() functions in drivers/scsi/scsi_debug.c. A local user can perform a denial of service (DoS) attack.
7) Use-after-free (CVE-ID: CVE-2021-47600)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the rebalance_children() function in drivers/md/persistent-data/dm-btree-remove.c. A local user can escalate privileges on the system.
8) Use-after-free (CVE-ID: CVE-2023-52752)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the seq_printf() and spin_unlock() functions in fs/smb/client/cifs_debug.c. A local user can escalate privileges on the system.
9) Spoofing attack (CVE-ID: CVE-2023-52881)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error within the tcp_ack() function in net/ipv4/tcp_input.c, which can result in system accepting ACK responses for bytes that were never sent. A remote attacker can perform spoofing attack.
10) Improper locking (CVE-ID: CVE-2024-26923)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper locking within the unix_gc() function in net/unix/garbage.c due to garbage collector does not take into account the risk of embryo getting enqueued during the garbage collection. A local user can execute arbitrary code with elevated privileges.
11) Improper privilege management (CVE-ID: CVE-2024-36964)
The vulnerability allows a local user to read and manipulate data.
The vulnerability exists due to improperly imposed permissions within the p9mode2perm() function in fs/9p/vfs_inode.c. A local user can read and manipulate data.
12) Out-of-bounds read (CVE-ID: CVE-2024-38599)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to an out-of-bounds read error within the do_jffs2_setxattr() function in fs/jffs2/xattr.c. A local user can perform a denial of service (DoS) attack.
13) Buffer overflow (CVE-ID: CVE-2024-42145)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to memory corruption within the MODULE_AUTHOR(), __get_agent(), send_handler(), recv_handler() and ib_umad_read() functions in drivers/infiniband/core/user_mad.c. A local user can perform a denial of service (DoS) attack.
