Vulnerability Details

CVEID:CVE-2023-5717
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a heap out-of-bounds write flaw in the Performance Events (perf) component. By sending a specially crafted request using the perf_read_group() function, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/269599 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2023-3772
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by a NULL pointer dereference flaw in the xfrm_update_ae_params() function in the IP framework for transforming packets (XFRM subsystem). By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause the kernel to crash.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/261635 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-39194
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by an out-of-bounds read flaw in the processing of state filters in XFRM. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 3.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/267516 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N)

CVEID:CVE-2023-39192
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by an out-of-bounds read flaw in the u32_match_it function in Netfilter Xtables. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 6.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/267514 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:L)

CVEID:CVE-2023-46219
**DESCRIPTION:**cURL libcurl could allow a remote attacker to bypass security restrictions, caused by a flaw when saving HSTS data to an excessively long file name. By sending a specially crafted request, an attacker could exploit this vulnerability to use files that unaware of the HSTS status.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/273321 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:CVE-2023-46218
**DESCRIPTION:**cURL libcurl could allow a remote attacker to bypass security restrictions, caused by a mixed case flaw when curl is built without PSL support. By sending a specially crafted request, an attacker could exploit this vulnerability to allow a HTTP server to set β€œsuper cookies” in curl.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/273320 for the current score.
