4) Resource management errors (CVE-ID: CVE-2009-4138)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to resource management errors error. A local user can perform a denial of service (DoS) attack.
5) Use-after-free (CVE-ID: CVE-2009-4141)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the fasync_helper() function in fs/fcntl.c. A local user can execute arbitrary code with elevated privileges.
6) NULL pointer dereference (CVE-ID: CVE-2009-4308)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to NULL pointer dereference within the ext4_decode_error() function in fs/ext4/super.c. A remote non-authenticated attacker can perform a denial of service (DoS) attack.
7) Integer overflow (CVE-ID: CVE-2009-4536)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel 2.6.32.3 and earlier handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload. NOTE: this vulnerability exists because of an incorrect fix for CVE-2009-1385.
8) Input validation error (CVE-ID: CVE-2009-4538)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel 2.6.32.3 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have an unspecified impact via crafted packets, a related issue to CVE-2009-4537.
9) Information exposure (CVE-ID: CVE-2010-0003)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to access sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to information exposure error. A local user can access sensitive information or perform a denial of service (DoS) attack.
10) Null pointer dereference (CVE-ID: CVE-2010-0006)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to null pointer dereference error. A remote non-authenticated attacker can perform a denial of service (DoS) attack.
11) Permissions, privileges, and access controls (CVE-ID: CVE-2010-0007)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to manipulate data.
The vulnerability exists due to security restrictions bypass error. A local user can manipulate data.
12) Security restrictions bypass (CVE-ID: CVE-2010-0291)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a local user to read and manipulate data.
The Linux kernel before 2.6.32.4 allows local users to gain privileges or cause a denial of service (panic) by calling the (1) mmap or (2) mremap function, aka the 'do_mremap() mess' or 'mremap/mmap mess.'
