OESA-2023-1781 — kernel security update

Affected: openEuler:22.03-LTS: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): An issue was discovered in the Linux kernel through 6.0.6. drivers/char/pcmcia/cm4040_cs.c has a race condition and resultant use-after-free if a physically proximate attacker removes a PCMCIA device while calling open(), aka a race condition between cm4040_open() and reader_detach().(CVE-2022-44033) An issue was discovered in the Linux kernel through 6.0.10. In drivers/media/dvb-core/dvb_ca_en50221.c, a use-after-free can occur is there is a disconnect after an open, because of the lack of a wait_event.(CVE-2022-45919) VUL-0: CVE-2023-2593: kernel: Linux Kernel ksmbd Memory Exhaustion Denial-of-Service Vulnerability(CVE-2023-2593) There is a null-pointer-dereference flaw found in f2fs_write_end_io in fs/f2fs/data.c in the Linux kernel. This flaw allows a local privileged user to cause a denial of service problem.(CVE-2023-2898) An issue was discovered in drivers/bluetooth/hci_ldisc.c in the Linux kernel 6.2. In hci_uart_tty_ioctl, there is a race condition between HCIUARTSETPROTO and HCIUARTGETPROTO. HCI_UART_PROTO_SET is set before hu->proto is set. A NULL pointer dereference may occur.(CVE-2023-31083) An issue was discovered in drivers/mtd/ubi/cdev.c in the Linux kernel 6.2. There is a divide-by-zero error in do_div(sz,mtd->erasesize), used indirectly by ctrl_cdev_ioctl, when mtd->erasesize is 0.(CVE-2023-31085) VUL-0: CVE-2023-32246: kernel: Linux Kernel ksmbd RCU Callb…

WID-SEC-W-2023-1255 — Linux Kernel (ksmbd): Mehrere Schwachstellen

Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um einen Denial of Service-Zustand herbeizuführen, Informationen offenzulegen, Sicherheitsvorkehrungen zu umgehen, Privilegien zu erweitern und beliebigen Code auszuführen.
