1) Race condition (CVE-ID: CVE-2024-24860)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition within the {min,max}_key_size_set() function in the Linux kernel bluetooth device driver. A remote attacker with physical proximity to device can send specially crafted packets to the system and crash the kernel.
2) Input validation error (CVE-ID: CVE-2024-26830)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the i40e_check_vf_permission() and i40e_vc_del_mac_addr_msg() functions in drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c. A local user can perform a denial of service (DoS) attack.
3) Memory leak (CVE-ID: CVE-2024-39484)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within the davinci_mmcsd_remove() and __exit_p() functions in drivers/mmc/host/davinci_mmc.c. A local user can perform a denial of service (DoS) attack.
4) NULL pointer dereference (CVE-ID: CVE-2024-36901)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to NULL pointer dereference within the ip6_output() function in net/ipv6/ip6_output.c. A local user can perform a denial of service (DoS) attack.
5) Double free (CVE-ID: CVE-2024-26929)
The vulnerability allows a local user to execute arbitrary code.
The vulnerability exists due to a double free error within the qla2x00_els_dcmd_sp_free() and qla24xx_els_dcmd_iocb() functions in drivers/scsi/qla2xxx/qla_iocb.c. A local user can execute arbitrary code.
6) Integer underflow (CVE-ID: CVE-2024-26921)
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.
7) Resource management error (CVE-ID: CVE-2021-46926)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the sdw_intel_acpi_cb() function in sound/hda/intel-sdw-acpi.c. A local user can perform a denial of service (DoS) attack.
8) Use-after-free (CVE-ID: CVE-2023-52629)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the switch_drv_remove() function in arch/sh/drivers/push-switch.c. A local user can escalate privileges on the system.
9) Use-after-free (CVE-ID: CVE-2023-52760)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the spin_unlock() function in fs/gfs2/super.c. A local user can escalate privileges on the system.
