Description

This security bulletin contains information about 6 vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2023-52606)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: 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/E:U/U:Clear


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the fp/vmx code in powerpc/lib/sstep.c. A local user can trigger memory corruption and perform a denial of service (DoS) attack.


2) Incorrect calculation (CVE-ID: CVE-2024-26645)

CWE-ID: CWE-682 - Incorrect Calculation

CVSSv4: 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/E:U/U:Clear


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to incorrect calculation within the __tracing_map_insert() function in kernel/trace/tracing_map.c. A local user can perform a denial of service (DoS) attack.


3) Integer underflow (CVE-ID: CVE-2024-26921)

CWE-ID: CWE-191 - Integer underflow

CVSSv4: 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/E:U/U:Clear


The vulnerability allows a local user to execute arbitrary code.

The vulnerability exists due to integer underflow within the nf_ct_frag6_queue() and nf_ct_frag6_gather() functions in net/ipv6/netfilter/nf_conntrack_reasm.c, within the ip_frag_queue() and ip_defrag() functions in net/ipv4/ip_fragment.c, within the FRAG_CB(), inet_frag_queue_insert(), inet_frag_reasm_prepare(), EXPORT_SYMBOL() and inet_frag_reasm_finish() functions in net/ipv4/inet_fragment.c. A local user can execute arbitrary code.


4) Out-of-bounds read (CVE-ID: CVE-2024-27042)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 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/E:U/U:Clear


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 amdgpu_discovery_reg_base_init() function in drivers/gpu/drm/amd/amdgpu/amdgpu_discovery.c. A local user can perform a denial of service (DoS) attack.


5) Memory leak (CVE-ID: CVE-2024-35930)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: 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/E:U/U:Clear


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within the lpfc_rcv_padisc() function in drivers/scsi/lpfc/lpfc_nportdisc.c. A local user can perform a denial of service (DoS) attack.


6) Use of uninitialized resource (CVE-ID: CVE-2024-36933)

CWE-ID: CWE-908 - Use of Uninitialized Resource

CVSSv4: 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/E:U/U:Clear


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to use of uninitialized resource within the EXPORT_SYMBOL_GPL() and nsh_gso_segment() functions in net/nsh/nsh.c. A local user can perform a denial of service (DoS) attack.
